Windows 8 won't boot

This concerns a Toshiba Satellite L75D-A7280.

Ran a Toshiba update and now W8 will not boot.

Attempted System restore... it looks good until the very end... Error 0x80070005 could not access a file.

Tried rebuilding BCD, etc.

Can only access drive via the boot DVD.

Renamed Default, SAM, etc... no joy.

Thoughts?



Is there a recovery partition on this machine? Try to start from the recovery partition and do a startup repair.

Otherwise, you may need to back up the system (boot from another CD) and reinstall Windows.

What toshiba update did you run?
You could either post here what the name of the update was, revision, etc, or can google it.
It sounds as though you updated the BIOS, which is a bad idea on anything that is working correctly. Bios updates are generally only to fix issues you are/were having, were there issues?
Assuming you ran the latest update, go to Toshiba's website and see what that adds, then boot into the bios, and change the setting to disabled for those added features, and see if you can boot, it would be helpful if you remember what revision you were on prior as well...


It is possible the drivers that are on your image don't support or know what the change is, which can cause this issue.



I am no longer concerned about reviving this PC... I'd be happy with resetting or refreshing at this point.

When I attempt a refresh it fails with a "drive locked" error. Tells me to unlock it.

Resetting will yield a, after a bit, "required drive partition is missing" error message.

System restore seems to appear to be working then, after finalizing, comes up with a "file access" error.

I can only boot to a W8 DVD and go from there. At a command prompt it appears that all files, etc are there.

Thoughts?



At this point rather then wasting time trying to fix it. If you don't care and have decided whatever to the file system.. Just reformat it..

Is there any errors when you boot from the CD and go through the method of reformatting it?
Does the system see the disk? or...?



I don't have a Windows 8 DVD... only the recovery methods available from the Toshiba
