Hi,
Vista x64 Ultimate here. My computer hung after crcdisk.sys. The Vista
DVD's repair stuff was not able to fix the problem, but I was able to fix it
myself.
1) Boot from the DVD.
2) "Repair my computer"
3) Cancel your way through anything the DVD tries to fix until you get to
the menu that has options like "Memory test", "Restore from backup", "Repair
startup"...
4) Open yourself a command prompt.
5) Notice you can even load notepad from said command prompt :-)
5.5) Maybe run chkdsk on your c: just to make sure there isn't any corrupt
files or indexes (chkdsk /f /x c

6) Go to Vista's System32\Drivers directory - usually
c:\windows\system32\drivers
7) Create a temporary directory somewhere on your disk for backup
8) In the drivers folder, do a "dir /od" to sort by date and look for all
the .sys files that are dated when you installed the hotfix. The KB article
on microsoft lists which files these are if you want to be careful.
9) Copy them all to your temorary folder for backup.
10) On the x: drive created by the DVD, you'll find original copies of these
in x:\windows\system32\drivers
11) Copy over the .sys files that were installed by the hotfix.
12) You should now be able to boot back into vista. Once in Vista, I
personally did a system restore to a point before I installed the hotfix, but
maybe somebody smarter than me knows a different thing to try.
