Windows detected a hard disk problem Solved
Windows detected a hard disk problem Solved
Windows detected a hard disk problem, what does it mean?
- Your hard drive is failing and may die sooner or later.
- You can lose all your programs, data, documents, videos, music and important images when your hard drive eventually failed.
- You may encounter freezes and not responding error.
- Your Windows operating system files may become corrupted and unbootable.
What to do when you receive this message “Windows detected a hard disk problem”?
- First, don’t panic, stay calm.
- Take heed of the drive partition (c:/d:, etc) that are failing and the one that aren’t. To save you time and concentrate on checking the failing partitions.
- Do a “CHKDSK“, by pressing “windows logo + r” simultaneously to get the “run” window.
- In the “run” window ? type “cmd”.
- Once you’re in the “command prompt” ? type the drive letter you want to chkdsk (be it c:/d:/e: and so on) or leave it as is, if you want to test the default drive partition.
- Then type “chkdsk” and hit “Enter” to start the “chkdsk”.
- After Windows scan your hard disk for errors it will give you good understanding on where and what is going on with your hard drive. How many bad sectors and other useful information.
However, if you want to directly full scan your hard disk for errors and let Windows do the automatic fix of system file errors as well as bad sectors, follow this guide:
How to run chkdsk and attempt bad sectors recovery?
Go to: “start” ? “my computer” ? “select the drive letter you want to check disk” ? “right-click it” ? “select properties” ? “tools” ? “check the ‘scan for an attempt recovery of bad sectors” ? “click start“.
Note: If you selected the drive that contains your Windows operating system, you will be prompted to reschedule the scan after restart.
Why should you perform a chkdsk on your hard drive when you encounter “Windows detected a hard disk problem“?
Someway or another “chkdsk command” may fix the error because it will mark the bad sectors and refrain from using it. Though, it is given, once this error “Windows detected a hard disk problem” keep on displaying, you’re hard disk is in extreme trouble—but sometimes it’s just the bad sectors which “chkdsk” will be of great help.
What if chkdsk command isn’t able to solve the “Windows detected a hard disk problem?
It’s time to back-up all your important data. As what I have mentioned earlier, remember those drive partitions that aren’t reporting failures. You can use those partitions to save your precious files. However, if your whole hard disk is failing, you need to have a new one or an old one from your old computer.Now that you backed all your important data up, what’s next? Is your hard disk repairable?
There is still a big possibility that your hard drive can be repaired. How? Try to reformat your hard drive using another computer—by “right-clicking” your hard disk ? select “format” ? uncheck the quick format ? Then, click start. You should format it without checking the “quick format”. It may take sometime, depending on your hard disk size but patience is virtue.
When you finished reformatting your hard drive, test it, re-install your operating system and observe it, if the error still appears. If there is none anymore, be glad but if it is still reporting “Windows detected a hard disk problem”—we will try another solution on my next post.

Turn an IBM X3100 M4 Server into a workstation
Turn an IBM X3100 M4 Server into a workstation
This is a neat little server that comes from IBM that officially doesnt support Windows 7. In this post I will guide you through making it run Windows 7 using the built in LSI Raid controller and a RAID mode.
If you decide to use AHCI mode however, it becomes easier (as it is supported by Windows 7), but you will be missing a performance (or stability) increase youll get with the RAID.
The LSI raid controller on this server does not have drivers that support Windows 7 - only Windows Server 2008 (R2). Theres also a great many driver packages available from IBM for this controller, so choosing the right one is quite time consuming. After 4 different failed driver packages I finally found the right one that would enable the RAID controller inside the Windows 7 installation PE. I have uploaded it HERE.
Just unrar and copy it onto a flash drive and browse to it during the installation (when it fails to find any hard disks).
Once the system finishes installing - most of the drivers will be installed, the only ones that wont be are the Chipset and the onboard video (Matrox G200ER2). Download the driver for it here.
Chipset drivers are available here.

Woman jailed for cutting houseboy with razor blade another sentenced to 2 years for buying a baby NAPTIP
Woman jailed for cutting houseboy with razor blade another sentenced to 2 years for buying a baby NAPTIP
The Violence against Persons (Prohibition) Act, 2015 has recorded its first casualty as a Federal Capital Territory High Court sitting in Kubwa, Abuja has sentenced a 29 year old housewife, Mrs. Onyekachi Okafor to 9 Months imprisonment for violating aspects of the Act.
This is coming on the heels of the conviction of Mrs. Mavis Solomon by a Federal High Court sitting in Port Harcourt, River State presided over by Justice A. Liman. Mrs. Solomon was charged by NAPTIP to Court for purchasing a 10 Months old baby at the cost of N200, 000 from 2 others who are also under prosecution. The offence is contrary to Section 21 of the Trafficking in Persons (Prohibition) Enforcement and Administration Act, 2015. She pleaded guilty and was sentenced to 2 years imprisonment.
Mrs. Okafor who resides at Dape, along Karmo Road of Abuja was dragged to the FCT High Court by the National Agency for the Prohibition of Trafficking in Persons (NAPTIP) on behalf of the Federal Government for willfully inflicting physical injury on a 10 year old boy (names withheld). The boy who served her and her family as a house help received severe razor blade cuttings from Mrs. Okafor, an act which is in violation of and punishable under section 2 of the Violence against Persons (Prohibition) Act, 2015.
Section 2 subsection 1 of the VAPP Act says,’’ A person who willfully causes or inflicts physical injury on another person by means of any weapon, substance or object, commits an offence and is liable on conviction to a term of imprisonment not exceeding 5 years or a fine not exceeding N100,000.00 or both’’.
Mrs. Okafor who was arrested by officials of NAPTIP in September 2015 had used a sharp razor blade to cut the victim on various parts of his body including his abdomen, left buttocks and thigh.
When the case came up on Monday, 4th July 2016, Mrs Okafor who was arraigned on a one count charge pleaded guilty of the offence. The presiding Judge, Justice N. Ogbonna therefore, found her guilty and sentenced her to 9 months imprisonment without an option of fine. No compensation was however, awarded to the victim.
It would be recalled that the former President, Dr Goodluck Jonathan signed the Violence against Person (Prohibition) (VAPP) Act 2015 on 23rd May, 2015. NAPTIP was made the implementing Agency for the new Act.
The Act which applies only in the Federal Capital Territory, Abuja, prohibits all forms of violence against persons in private and public life and provides maximum protection and effective remedies for victims and punishment of offenders.

This is What Happens When you Shoot a Gun Underwater!
This is What Happens When you Shoot a Gun Underwater!
Andrew recently shot some handguns underwater and captured the results using a Pentax WG-2, a waterproof digital camera capable of taking basic high speed videos (which can be seen below). It’s interesting to see that the bullet does not travel very far underwater. The hollow point bullets also appear to blossom, almost turning inside out.
Andrew remarks that the pressure underwater from the blast feels like someone is punching you in you chest. He also said he fully inspected each handgun and did not detect any damage. Most important is that the sound/pressure underwater can be intense so sticking your head or ears underwater is obviously dangerous and not recommended.

Tips to buy a laser color printer
Tips to buy a laser color printer
Color laser printers are increasingly smaller physique, rushed in print, and cheap price. You can get a price ranging from U.S. $ 300. Therefore, one should pay attention to the color laser printer is not just the price of the affordable unit, or the speed of printing and paper tray capacity. But also the operational costs. Remember, the price of consumables is high.
Because its possible the color laser printer is a low-end price in the range of U.S. $ 500 in the end be more costly than clever in price range of U.S. $ 500 - U.S. $ 1000 or more due to the speed, capacity larger paper: cost per page becomes cheaper.
For example, if EP316 Black toner for Canons Laser Shot LBP50550N/5050 sold U.S. $ 78 and can be used to print 2300 pages, meaning the cost per page printing monochrome (not including the price of paper) on the color laser printer is 3.4 U.S. cents.
Meanwhile, black toner for brother EP302 Black, Canon Laser Shot LBP5970, sold U.S. $ 150 with a capacity of 10,000 printed pages. That is, monochrome printing costs per page (outside the paper) with Canon Laser Shot LBP5970 to 1.5 U.S. cents, or about 44% cheaper. But in terms of unit price, Canon Laser Shot LBP5050N the 8ppm color print speed, and can be connected to the network is far below the Canon Laser Shot LBP5970 ($ 520 vs. U.S.. U.S. $ 3600).
So what to look for when going to buy a color laser printer? Here are some consideration.
Speed
Before buying any printer, used to count how many pages are printed each month your office. After that, examine the engine speed and monthly duty cycle of the printer you are considering, to see whether your use pattern in accordance with printer capabilities.
Printer engine speed, expressed in pages per minute (ppm - page per minute) tells how fast the printer to work in ideal conditions (or even the special conditions created by its vendor).
Canon Laser Shot LBP5050N/5050 for example, capable of printing 8ppm for color or 12ppm for black and white. While Canon Laser Shot LBP5970 can drag almost four times: 30ppm to 32ppm for color or black and white on A4 paper. Speed Canon Laser Shot LBP5970 slowed as printing on paper that is wider, the size of A3: 15ppm for color and monochrome.
The average printer, according to tests conducted by PCWorld, reaching only 75% of the maximum speed is mentioned. Even according to PCWorld, the speed of color laser printer is the cheapest way below its vendor claims.
But still the engine speed is the easiest guide to find out if the printer can handle your daily printing needs - personal or in the office. More and more people are using the printer, the more you print, so the faster the printer should do. Except if you like girl talk near the printer with fellow colleagues, looking at who the print jobs come out ahead.
Thorough also how fast a laser printer to respond to your commands perform tasks from the state printing die or standby mode. There are several printers that must warm up first before you can print. As a result you have to wait a while - could be a matter of seconds or even minutes - first.
Why? In most conventional laser printer, there is usually a roller fixing the entire surface must be heated first before printing can begin to do. This is what causes the heating time (warm-up time) that can be quite long - depending on the extent of the surface of the roller.
But there is also, like the Canon Laser Shot LBP5050N/5050 and Canon Laser Shot LBP5970, who claimed zero warm-up time, aka do not require warm-up time. If any, time is very minimal.
This is because all Canon laser printer uses Canons On-Demand Fixing. Here, a thin fixing film heated directly by a ceramic heater. Because direct heat transferred to the fixing film, the print process can be done without waiting for another warm-up time. Live press the Print button, and instantly print out the results. With On-Demand technology Fixing, according to Canon, Laser Shot LBP5970 Laser color it only takes about 7.5 seconds to be ready to print from the printer activation button (standby mode) lit.
In addition to the print speeds and warm-up response time, precise duty cycle is also a printer. Duty cycle or duty cycle determine the manufacturing threshold for the maximum number of pages printed per month. Youll want a wide range between minimum and maximum mold so freely in print.
Entry-level printers typically have a duty cycle of 300,000 pages per month. Printer at a price of around U.S. $ 1000 duty cycle typically offer an average of 60,000 pages per month, while the weight class printers, high volume, which cost in the range of U.S. $ 1000 - U.S. $ 2000, offering an average of 100,000 pages per month.
Print Resolution
Actually, we need an optical resolution of a fuss about the printer, the exact number of dot per inch that can be printed? Probably not. Color laser printer is the cheapest one is showing an optical resolution of 600 × 600 dpi, which is suitable for most business needs.
Many vendors are also implementing specific algorithms to emulate higher resolutions, such as Canon Laser Shot LBP 50550N/5050 offers a maximum resolution of 9600 × 600 dpi through techniques AIR (Auto Image Refinement). But some, like the Canon Laser Shot LBP 5970, which was offered resolution 1200 × 1200 dpi true.
But if you do not really want the print quality is excellent, just ignore the higher resolution. Moreover, you must be prepared to wait longer to get the results printed.
Which is also an important factor considered is the cost per page to operate the printer. Consumable printer includes all the specification that tells how many pages will be printed by the unit. Depending on what you print, the number you get will be different.
Color laser printers are usually cheaper mengemaskan small capacity toner cartridge - only tolerate a few thousand pages to print. Canon Laser Shot LBP5050/5050N for example, providing EP316 Black toner is resistant to print 2300 pages, and EP316 CMY (cyan-magenta-yellow) with the capacity of each print 1500 pages.
Toner prices are generally expensive, so if you can save, print in color Save. If printing color can not be avoided, then you need a machine that its toner cartridge can print more pages; so the cost per page is lower, and of course do not have to be replaced often. Canon EP302 Toner Laser Shot LBP5970, have the capacity to print 10,000 pages black, while for the color magenta, yellow, and cyan each bear print until 6000 pages,
In most color laser printers (especially low-end), the toner cartridge is included toner, imaging components and toner remaining in the reservoir in a closed place. While supporting the practicality of daily operations, such as the design is actually more expensive in the long run, because all the parts you need to replace at once.
On some printers, particularly high-class models, these components are separated. Just did a new install takes skill and finesse, but in the long term operational costs will be cheaper. Examples include Canons Laser Shot LBP 5970 drum cartridge offers CMYK EP302, respectively 40,000 page print capacity.
Note that some upper-class printers are now bundling low-capacity toner cartridge, which is labeled as a "starter". For example Canon Laser Shot LBP5050N/5050. Starter toner CMYK packaging his own capacity only 800 pages, while the standard-capacity print until 2300 pages (black), and 1500 pages (CMY). Starter toner usually do give a yield less than half the replacement cartridge / normal. Therefore, try to ask for a bonus toner cartridges at a discount when buying a laser printer.
Paper Handling
The great difference between the color laser printer located in his handling of paper - the number and size. The main paper tray on the printer cheap (under U.S. $ 500) usually accommodates a maximum of 250 sheets of paper. Often no available option to add additional paper tray. In addition, these printers are generally not able to handle paper larger than legal - the only way to do this is to use the manual feed tray, like the Canon Laser Shot LBP5050N/5050.
For printers with a more expensive price, available paper trays for up to 600 sheets of paper (midrange), or even nearly 1200 pieces on a higher model. Canon Laser Shot LBP5970 offers a tray (feeder cassette) optionally up to three levels, each power capacity 500 sheets, so that in total (including the standard tray with a capacity of 100 sheets) this color laser printer can accommodate up to 2000 sheets of paper.
Paper tray on midrange models almost always receive a paper letter and legal sizes. Wide format printer or A3 as Canon Laser Shot LBP5970 can receive a tabloid-size paper, suitable for printing booklets. Besides the size of A3 and A4, Canon Laser Shot LBP5970 quite flexible in accepting other varieties of paper sizes: B4, B5, Letter, EXE. Legal, as well as paper and card with a thickness that varies:
Check also if the printer can print on photo paper, transparencies, stickers sheet CD / DVD, or envelope. Usually manual tray feedback should be used to print the job.
Color Accuracy
All the color laser printer is equipped with calibration feature to check the consistency of color. This order prints to 20 of your brochure will be the same color as the first printing. High-end printers to do the calibration after 40 to 50 copies; other printers do after printing a few hundred copies.
Color is also determined by the toner you use. Each vendor printer toner always recommend the use of the same brand to brand printers for color accuracy and permanence of age use the printer. And more and more available third-party toner is cheaper.
Memory
All users want speed printer would print a hurry and of course the excellent print quality. Print speed, especially for printing in large numbers, are also influenced by the memory (RAM) from the printer itself. Higher dikemaskan memory in a laser printer, usually the better (read: fast printing process).
However, this does not mean that a laser printer should always pack large amounts of memory. Theres a printer that can share the task of printing those with memory from a PC connected to the printer. So although the data should be printed large and complex, such as charts or maps of the room of an area, the process can still be printed in a high speed without the need to add more memory to the printer. Because the printer will print with the task of dividing the PC memory.
Models Canon color laser printers are usually adopted this technique, which it’s called the Canon Ultra Fast Rendering II (UFRII) and Load Balancing Technology. Canon ordained nine seconds as the length of time for printing a color document with a high level of complexity at a resolution of 9600 × 1200 optimized dpi for the printer model Canon Laser Shot LBP5970 this packed default memory of 256MB DDR SDRAM. But of course if you want and order to boost the speed faster, you are welcome to add additional memory / optional, such as 512MB.
Save Energy
In the global economic situation is still in shock, is also important to choose a laser printer that is not wasteful electric power. Indeed in the offices or even homes, laser printers are usually more often unemployed (idle), and instead print continuously without stopping. Because it is important to choose a laser printer is the electrical minimum intake while in this idle condition.
One can glance, especially if the print needs of your office include A4 and A3 paper - color or monochrome - is Canon Laser Shot LBP5970. In the sleep mode (sleep), this printer requires only 1W of power intake, which according to Canons 96% smaller than similar models from rivals brands.
Warranty
Do not forget to ask for warranty card to the printer that you buy. Ask also if the printer return policy is corrupt or jammed.
Other Features
Oh yeah, try to create a specification comparison table from a laser printer that you want to buy. Do not forget to include also the price of the printer unit and its toner prices. This is necessary for you to know what you can get from a particular brand and model, and whether it will meet your printing needs today and also in the future. There is no laser printers are made identical, so you do have to very careful in doing the specifications and price comparisons.
Compatibility for example, need to be given special attention. All laser printers that have been circulating today is not a problem when dealing with computers that Microsoft Windows operating bersistem. But check whether the laser printer is also compatible with other operating systems: Apple Macintosh and Linux.
Network capabilities and management of long-distance (remote) and ease of maintenance becomes something important, especially if the color laser printer will be operated in any office, ranging from small scale to medium scale up. The existence of port USB 2.0 Hi-Speed is required specifications. Also it would be nice if it was embedded 10Base-T/100Base-TX connector, and supporting applications to facilitate network management.

Windows 8 and Linux on a Toshiba Satellite Laptap
Windows 8 and Linux on a Toshiba Satellite Laptap
Windows 8 and Linux on a Toshiba Satellite Laptap
About a week ago, I got a new laptop: a Toshiba Satellite C855D-S5351. With the $50 rebate and $120 instant savings available on it at Office Depot, I thought it was going to be a great deal for $329. Perhaps, if I only wanted to run Windows 8 on it, I would be satisfied, but because I also want to run Linux on it, Ive had to struggle to get a few things working.
First, in order to make Windows 8 livable, I would recommend installing Classic Shell. You can download it from http://www.classicshell.net/. As shown in the screenshot, Classic Shell not only provides the Start Menu that is missing in Windows 8, but a greatly improved Windows Explorer. The menu can even look like the version of a Windows Start Menu that you like the best. I really like locating things where they always have been in Programs or the Control Panel, as well as the Windows key on your keyboard will now activate this menu. When you want to go to the Windows Metro look, you can either Alt-tab to the App, or move over the right side of the screen, and activate the Start icon.

When you want to go to the Windows Metro look, you can either Alt-tab to the App, or move over the right side of the screen, and activate the Start icon.
Preparing to Install Linux on a Windows 8 System
Before you do anything to your hard disk, you should make a "Repair Disk Windows 8 64bit". Point to upper right, click the Search icon, select Settings, and then click in the box to type "drive". Choose the option to create a recovery drive. It can be a USB disk, CD or DVD. Warning: If you dont create a Repair Disk, then Windows 8 may not boot and it may not be easy to fix. You should also create a new Repair Disk after successfully completing any changes to your hard disk.
Although I didnt make the recovery disk until after I got in trouble installing Fedora 17, I was able to get Windows 8 to boot after installing Linux. I was able to get it to recover by using a Live GParted CD. After booting the CD, I right clicked the Windows Recovery partition, and I set it the flags on it to include "boot". You may not be so lucky!
Create Space to Install Linux Using Disk Management
Select the largest partition and right click to choose to shrink it.
At minimum, you will want to shrink it by at least 10Gb, but with a 640Gb hard drive, I was able to shrink mine by about 400Gb.
Next, to be able to boot the DVD to perform an install, I used the following procedure to switch to BIOS, disable Secure Boot, enable CMS (compatiblity booting), and boot an install DVD.
At first I tried installing CentOS 6, and it succeeded nicely, but without ethernet support by default. I never got wireless working, although I think it may be possible using the compat-drivers discussed below.
When I quickly tired of the lack of available current packages from CentOS 6 (and other related repositories), I wanted to upgrade to Fedora. I tried the latest Fedora 18, but unfortunately, the brand new installer failed. So, next I tried the Fedora 17 DVD install and it succeeded. I was able to get ethernet, wireless, bluetooth, radeon, and other drivers working successfully.
Booting From Windows 8 to Linux
After booting, click the screen or log out of your accountClick the power icon in the lower right corner and choose Restart
Press F2 when Toshiba logo appears
Use arrow keys to navigate to Security menu
Go down until you arrive at Secure Boot
Press Enter to change the value, use arrows to change to Disabled, press Enter to go back
Up to the top, over to the Advanced menu
Down to System Configuration, and press Enter.
Down to Boot Mode
Press Enter to change to value to CMS Boot, and Enter to go back. (Press F10 and Enter)
Press Escape to go back to the top level menus.
Go up and over to the right to the Exit menu
Select Exit and save changes
When you want to come back, then follow this procedure:
Booting From Linux to Windows 8
RestartPress F2 when Toshiba logo appears
Over to the Advanced menu
Down to System Configuration, and press Enter.
Down to Boot Mode, and press Enter
Use arrow keys to change to value to UEFI Boot, and press Enter
Press Escape to go back to the main menus
Go up and over to Security menu
Down arrow until you arrive at Secure Boot, and press Enter
Use the arrow keys to change the value to Enabled and press Enter (Press F10 and Enter)
Go up and over to the right to the Exit menu
Select Exit and save changes
Boot into Windows 8
Ethernet networking
The Atheros ethernet device is shown on the PCI bus with lspci -nn as:01:00.0 Ethernet controller [0200]: Atheros Communications Device [1969:1090] (rev 10)
There is no driver for this device yet in the kernel, although one is proposed according to http://www.linuxfoundation.org/collaborate/workgroups/networking/alx.
From this document I found the source that is used to make the alx.ko kernel module needed for wired networking. The procedure there will only enable the ethernet driver, but not the other compat-drivers. Once built, this alx kernel module worked well in Fedora.
If you only want ethernet support then the procedure to build the module with the compat-drivers download is:
./scripts/driver-select alx
make
sudo make install
Making (Almost) All the compat-drivers
Since the radeon driver is already working in Fedora, and the one from the compat-drivers doesnt work so well, I didnt want that driver to be built and installed. So, I commented out building the radeon driver in the drivers/gpu/drm/Makefile.I did want to have the wireless driver built, but there was a problem in the source I downloaded with building another wireless driver (wil6210), so building all the drivers wasnt working. Since I didnt need this driver, I commented out building the wil6210 driver in ./drivers/net/wireless/ath/Makefile, as explained below.
Getting Wireless and Wired Ethernet Working
The Toshiba Satellite C855D-S5351 laptop that I using has a Realtek Wireless network interface which uses the rtl8723ae kernel module as a driver. This driver is also not included in the main stream kernel,, but is a part of the compat-drivers package.In order to build everything except the radeon driver and the wil6210 wireless driver that refused to build, I made the following changes:
First, to not build the radeon driver, the file ./drivers/gpu/drm/Makefile had to have the line changed from:
obj-$(CONFIG_COMPAT_DRM_RADEON)+= radeon/
to by adding a # at the beginning of the line:
#obj-$(CONFIG_COMPAT_DRM_RADEON)+= radeon/Second, in the ./drivers/net/wireless/ath/Makefile, the following line originally appeared as:
obj-$(CONFIG_WIL6210) += wil6210/
To stop building this driver a # was added to the beginning of the line like:
#obj-$(CONFIG_WIL6210) += wil6210/
Once these changes are made to the two Makefiles, then you are ready to build and install the drivers with:
make
sudo make install
Centos/Redhat
Although I had no success getting the compat-drivers to be built under Centos or Red Hat Enterprise Linux, I found a couple of potential solutions. There is a repository compatible with RHEL that exists at http://people.redhat.com/sgruszka/compat-wireless.repo.Also, there is the "El Repo" repository for the ethernet driver, and instructions for configuring this repository at http://elrepo.org/tiki/tiki-index.php. Using another Internet connected machine, I did successfully use this repository to download the kmod-alx driver and get it to work with Centos 6.
Fedora 17
Installation of Fedora 17 did present one challenge. The installer would not continue past custom partitioning (I wanted to preserve my /home partition). It complained about not having a BIOS Boot partition for Grub 2. The installer would automatically create this partition in automatic partitioning mode, but provided no way to do it manually in the custom partitioning mode.With UEFI, systems dont use a "MS-DOS Partition Table" on the hard drive, instead they use "Guid Partition Table" or GPT type. The partitioning tool fdisk does not work with GPT partitions, so something like parted or gparted needs to be used instead. Since parted can be very challenging and unforgiving, I decided against using it, even though I could access it from the installation shell.
The solution I used instead to create a special partition with the boot_grub flag set was a Live CD version of Gparted from http://gparted.sourceforge.net/download.php. Once the CD was booted, I created a 10Mb partition, and right-clicked it to set the boot_grub flag on it. Once this partition existed, then Fedora 17 was able to use custom partitioning successfully during installation.
Windows 8
After all seemed well with the completed Fedora installation, I attempted to boot back to Windows 8. Unfortunately, after following the above procedure to go back to UEFI and Secure boot, I encountered an error message about not having any bootable partition. GParted Live CD to the rescue again! Using GParted, I right-clicked the Windows Recovery partition, and set its flag to boot, and applied the change. Surprising Windows 8 booted right back up without any apparent issues.
Conclusion
It is possible to use both Windows 8 and Linux on the Toshiba Satellite C855D-S5351 laptop. Although I disabled Secure and UEFI booting in order to make it possible. Next, I may explore the possibility of installing Linux using Secure UEFI booting, as several distributions claim that capability.
Soon, the Atheros alx kernel module for wired ethernet networking should be in the mainstream kernel. Reportedly, the Realtek Wireless rtl8723ae kernel module may be reworked and merged with other similar modules for Realtek Wireless devices, so it may also be available in the mainstream kernel in the near future. For now, theres compat-drivers, compat-wireless, and various repositories around to enable the use of both wired and wireless networking.

The Titanic sails again Australian tycoon unveils plans for perfect replica of doomed vessel except with a few more lifeboats
The Titanic sails again Australian tycoon unveils plans for perfect replica of doomed vessel except with a few more lifeboats
With a name like Titanic II its launch was never going to be plain sailing.
The sequel to the doomed liner that sank 100 years ago was announced on Tuesday - after its designer claimed it would be the most safe cruise ship in the world with ample lifeboats.
With hubris akin to that of the 1912 original, Markku Kanerva said that from a safety perspective there was no vessel on Earth which compared to the new boat.
Scroll down for video.
He said that it had more than enough lifeboats and that the hull was stronger than the wooden original because it was made from steel composite.
Despite his confidence the mastermind behind the project, brash Australian mining billionaire Clive Palmer, refused say it was unsinkable.
He said: I think anything will sink if you put a hole in it. I think youd be very cavalier to say something like that.
I think people in the past have done that and lived to regret it.
The blueprint for the Titanic II was unveiled in New York for the first time along with computer generated images of the inside.
They bear a startling resemblance to the 1997 James Cameron film about the ship, which starred Kate Winslet and Leonardo Di Caprio, and show that many of the original features including the famous Grand Staircase will feature in the new boat.
The six-day maiden voyage will take place in late 2016 and will be be from Southampton to New York to complete the journey started all those years ago.
Just like in 1912 there will be three classes of passenger and those with different tickets will not be able to move between the classes, though there will be more toilets for the lower decks than the original.
Everyone on board will however be provided with early-20th-century-style clothes and undergarments in their cabins to get them in the mood.
Whilst there will be air conditioning there will be no TVs and no Internet in a bid to get back to the romance of a bygone age.
Professor Palmer outlined his bold vision in which the Titanic II would be carrying the hopes and dreams of people everywhere and represent the reconciliation of man.
There will be capacity for 2,435 passengers and 900 crew.
There will also be lifeboats that can carry 2,700 and a life rafts with an additional capacity of 800.
The original Titanic had just 16 wooden lifeboats that accommodated 1,178 people, one third of the total capacity.
Some 1,502 people died when it sank on April 15 1912.
It was one of the worst peacetime disasters the world has ever seen.
At the launch of Titanic II, which began with a guitar rendition of Celine Dions My Heart Will Go On, Professor Palmer explained that the ship will be 883ft long, which is three inches longer than the original.
It will have a tonnage of 55,800 tonnes compared to 53,210 of the original.
It will have a maximum speed of 24 knots, the same as the first Titanic.
Other original features which will also appear on Titanic II include the Turkish baths, the Cafe Parisien, the two Millioniare Suites, the Chart Room, and the quarters belonging to Titanic Master Captain Edward Smith.
For entertainment guests can enjoy the casino, cinema or shopping area.
The blueprint shows that there will even the same Marconi room where the Titanic sent out its final SOS.
Whereas the original was built by the famous Harland and Wolff shipyard in Belfast, in a sign of how times have changed the Titanic II is being constructed by state-owned Chinese company CSC Jinling Shipyard.
Professor Palmer refused to reveal how much he is paying to build Titanic II but claimed there had already been significant interest, including from celebrities.
He said: 40,000 people had registered for tickets on the ships website with 16 offering between $750,000 and $1m to be on the opening voyage.
He added that on the first trip he would be in third class twiddling the fiddle like Leonardo Di Caprio did in the film.
Mr Kanerva, of Finnish boat designers Deltamarin, added: I can assure you that from a safety point of view it will be absolutely the most safe cruise ship in the world.
We are taking into account all of the possible incidents and accidents and we try to simulate all of those occasions.
Collision is the most common accident we are talking about.
The launch, on the USS Intrepid moored on a pier in Manhattan, was met with a mixed reaction by relatives of those who survived the original sinking.
Helen Benzinger, the great granddaughter of Molly Brown, an American heiress who was on board Titanic, said that she was thrilled at the new design.
The family of the Capt Smith however have said the replica is in bad taste.
