I've been searching endlessly for help with this one.
Vista x64 up and running fine for a few weeks - had a sudden power outage.
Now cannot boot into windows - was getting hungup at the crcdisk.sys during attempts to get into safe mode.
I have tried:
1: Running the 'repair' option from my windows CD
Results: Now when it gets to where the 'login' screen should be, i get a blank 'error window' with no text. If i close it it pops up again. (Same thing happens in safe mode).
(It actually booted into windows the first time after running 'repair' - except there was no text anywhere - not on the icons, in the start menu, nada. Couldn't shut down properly, had to hard reset.)
Next I tried running chkdsk /f from the boot CD - still the same.
