After a recent Windows 8 update, my computer refused to boot properly, but attempted an Automatic Repair, which was unsuccessful. The system would flash a blue screen of death and reboot with no more illuminating error message. I also encountered this when booting from the Windows 8 DVD – sudden blue screens with no error messages.
My Windows 8 installation is on a SSD on a system with an AMD chipset, and I had to switch the SSD to IDE mode access to get any sort of stability. After I did this, Automatic Repair had a longer attempt to fix it, but still ended unsuccessfully with a message informing me to check WINDOWS\System32\Logfiles\Srt\Srttrail.txt. Removing the SSD and examining this file on my laptop showed me the following error message:
Boot critical file E:\Windows\System32\drivers\amdsbs.sys is corrupt
Replacing that file with a fresh copy did not appear to help. To get Windows to boot properly, I had to boot to a command prompt (clicking the Advanced Options button from the screen with the Srttrail.txt error message) and use the dism.exe tool with this command:
dism.exe /image:D:\ /cleanup-image /revertpendingactions
where D: is the Windows drive.
After doing this and rebooting, on the next boot Windows detected a failed update and reverted changes. I was then able to enter Windows.
The update at fault appears to be KB2836988 and I suspect it may be causing problems with systems using the AMD 700 series chipset. Other people seem to be experiencing similar problems. We will see whether Microsoft do anything to address the problem; in the meantime, I’ve turned off Automatic Updates, and am avoiding that particular update for the moment.
