When I try to boot Windows 8, it starts automatic repair process which fails to repair it. It logs stuff in c:\windows\system32\Logfiles\Srt\SrtTrail.txt. After one of attempted automatic repairs, last line in that file said that tm.sys and clfs.sys files are corrupt (current version says "Startup Repair has tried several times but still cannot determine the cause of the problem.")

Any ideas how to fix this? Thanks in advance.

Have not tried this on W8, boot from the W8 install media and choose "repair your computer" to load the tools, then follow this guide to run a sfc offline – Moab Nov 11 '12 at 5:51
I ended up reinstalling windows, nothing else would help. I also found some corrupt files afterwords... – Viet Norm Nov 12 '12 at 2:24
I'm having the same issue. PC started acting real slow and I hit the reset button. Afterward the system failed to boot properly. Pathetic how fragile the windows bootloader is. – dcompiled Nov 24 '12 at 20:41

The easiest way to go about this is reinstalling windows 8 and by the tag I'll guess it's 8.1

This should help for future reference and anybody else.
