When I press the power button, it shows "no bootable device-Please restart system. Your pc ran into a problem and needs to restart."

 

1] I changed the Boot order to boot Knoppix but then I get:

"Boot Failure: a proper digital signature was not found. One of the files on the selected boot device was rejected by the secure boot feature"

 

then the laptop shuts down.

 

2] I also see the options to go into safe mode but it doesn't work and the system restarts itself.

 

3] I tried doing a factory recovery by holding down the 0 key as it suggests here:

but that does not work with the system restarting itself.

 

4] Now I am seeing: Repairing disk errors. This might take over an hour to complete"

 

If the above no.4 does not work, I am thinking I can try running a chkdsk but how can I do so from outside of windows? BTW, I am now sometimes hearing a "clicking" noise every now and then, I am guessing this is coming from the HDD while the system is trying to repair it?

The repair did not work, it restarted itself after showing another error message then shows now "Diagnosing your pc"

Your hard drive bit the dust, Mike.

If that is the case Cindy, any idea why Knoppix would not load?

I've always been told that the HDD is unrelated to a linux OS and is one way to know if the HDD is bad [if the linux loads and runs properly]?

I'm not sure, Mike. I would expect that it should load as I think it actually runs from the optical drive.

BTW, right now it looks like it's accepting a fresh install of win8, will let you know.

Let us know how you fare, Mike because that doesn't mean the hard drive isn't bad.

I have suspected problems with the HDD since I started with this but just trying to see what happens

I have a feeling something's up with the HDD but was able to reload win8 64 bit but looking for the correct wireless and usb drivers, I tried these drivers here but reloading only 2 drivers are showing as yellowed in the device manager, the wireless and usb drivers, I can connect to the net wired but can't seem to find these 2 drivers. I looked at this thread:

http://forums.toshiba.com/t5/Drivers-and-Utilities/Satellite-C855-S5347-drivers-missing/td-p/475183

 

and tried those drivers but when I try to run it, it shows "Sorry. We do not support this operating system?

Did you install the chipset first, Mike? Is this a Satellite C855-S547?

Oh sorry I did not give the model number it is c855-S5347

I tried the Atheros wireless LAN driver but getting a message: windows has detected a hard disk problem.

 

I am not seeing a chipset driver on that page?

Oh I see, sorry I missed that but still nothing seems to work with those drivers so I am thinking it's safe to now to replace the HDD?

Definitely, Mike. :agree:

Mike working in Windows 8 to boot to cd, and every pc is different, you have to kill secure boot in the bios and choose legacy boot so that you can boot to cd drive in the first place. On some laptops there is a button on the surface that will accomplish the same thing meaning setting up booting from optical drive. Sorry I didn't see this post earlier. As you both know the problem is the hard drive though.

So I am trying anew HDD and disabled the Secure boot but when it comes to the 'Where you want to install windows" screen and I select the partition, I am getting an error message stating:

 

"Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT disks.

 

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's bios menu"

 

I am not seeing the "disk controller" anywhere in the bios?

How large is the disk Mike. Disks larger than 2.2 Gb have to be initialized as GPT. UEFI bios also has to be initialized to GPT which is why I said you must enable "legacy boot" to use normally to MBR.

The disk is 500gb, I am not sure how/where to find the legacy boot option? In the Advanced tab, I am seeing 2 options for boot mode [uEFI and CSM boot]

Me neither it could be in a different location in every bios but it is there usually around the boot drive order somewhere.

It's ok, I used Gparted to convert the disk to GPT, installing win8 on the new disk now, will let you guys know in a few.

good job!

Well it was the HDD, new HDD works lightning fast and no wireless issues, only the dvd doesn't autoplay.
