We ran TDSSKILLER on  Windows 7 x64 machine and now on reboot we get a BSOD stop x7b.  When trying safe mode it auto reboots after CLASSPNP.SYS.  Any suggestions on how to figure out which driver was removed or altered by TDSSKILLER?

I would say that it is having trouble identifying the boot device. Run the 7 DVD and let it repair the system error.

HTH,

I already tried that, it finds nothing wrong.  I tried a restore and didn't work.

It detected a MBR virus.
Grab a data backup first and then try fixmbr using command prompt

TDSSKiller doesn't handle TDL4 well in Windows 7.

bootrec /Fixmbr command from the Recovery Console should fix it.

I forgot to post yesterday but yes rpggamergirl is mainly right.  TDSSKILLER killed the "boot" folder.  using bootrec did the trick.  I however did the following:

http://support.microsoft.com/kb/927392

bcdedit /export C:\BCD_Backup
c:
bootrec /RebuildBcd
bootrec /FixMbr
bootrec /FixBoot
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd
bootrec /FixMbr


yes I know several commands were redundant, I was at a point where I could not even boot to the repair widows without getting a stop error, I did boot off the DVD went to the Advanced section of the repair so I could get to the command prompt, after running the commands as I mentioned above it finally recovered.  It is important to note simply following the article mentioned above will not work.  rpggamergirl got it in the fact that the MBR was gone/corrupt and was the cause of the driver failures I a positive.  I read lots of other people losing a windows install after running TDSSKILLER, you must check for the boot folder if it is missing that’s the issue!!
