Crash during Vista SP2 install.. ouch!

[kisk]

Was installing some updates for a client and SP2 was installing when I received random restart (driver) during the stage two of the reboot. Now I can't get it to boot up in reg or safe mode.

She's running 32bit vista home premium.

So it looks like the following files are corrupt:

Classpnp.sys
crcdisk.sys
disk.sys
ecache.sys

I tried copying over these files from a 64bit vista home premium machine but I'm still getting problems. After transferring those files my safe mode gets to mup.sys then goes straight to the repair wizard. I have a 32bit version of vista installing elsewhere to see if those files will work. Do the 64vs32 versions of vista use different versions of these files?

Any suggestions? Would rather repair this than have to wipe her comp. She's waited rather patiently.

Installing a SP on Vista always creates a restore point. Did you boot into repair mode and try to go back to the pre-SP point before doing anything else ?

yup, zero restore points found, which is bs because I always create a restore point when I first boot up a system

Very weird. If an SP was installing it really should have done it before, without operator intervention.

Wouldnt hurt to slave it and scan for viruses too. Some new ones will kill restore points.

Yea the system was brought to me as a virus removal job. Had the winlogon86.exe bug + a slew of others and I had everything cleaned up and re-restore-pointed after the clean. Been giving my clients free winupdates as part of my current special (yea, bout to stop that after this lol)

Any ideas what to do next considering I don't have any restore point to work with? Still waiting on a separate vista sp2 install to finish before I try to copy the files over.

Nah, not without sitting in front of it. Sorry.

Did you miss something?

Are you sure you got all of the malware, did you check also for spyware, adware, rootkits? you didn't install the SP while online did you?

Have you tried starting in last known good configuration?

I'm not sure but I think the main differences in 32 and 64 is in the way they handle the CPU and RAM and all of the drivers will be different.

If nothing else works you may want to remove the SP2 manually. I had a clients PC do only two updates and then rebooted with the BSOD, I went in and removed the updates and it started normally.
