[Solved] Please help virus destroyed BCD - no error message
Hi, I'm writing this from a KNOPPIX Live CD as my computer cannot boot.
I have a triple boot system (7, vista, XP) and Windows 7 is my main OS. I was using it to surf the web only a few hours ago and suddenly my anti virus software which is Avast! (free) started popping windows about a program being blocked, I did not have enough time to read it but the title of the window was vid<something>.info , the "<something>" is the part I don't remember. Also, there was the name of the executable of the program and it was 4 letters, something like vwfv.exe , again I hadn't much time to look because after a few seconds a window popped up in the top left corner and immediately the screen went black for two seconds and then showed a BSOD but this was not a regular BSOD, it only had a few words in the top left part of the screen. I pressed the reset button and the computer passed POST but did not show the Windows 7 boot manager. There was no error message, only a blinking cursor in the top left corner.
I inserted the Win7 DVD and chose to repair windows. It said it found problems and restored the BCD and that the old BCD is backed up. I rebooted but nothing was changed - still only a blinking cursor. I booted the W7 DVD again and this time it let me to the advance repair options. I chose Command Prompt and verified that my files were still there - they are, so I believe the MBR and HDD data are OK it's just the boot process files that got sabotaged by the virus.
I tried to run SFC /SCANNOW but it won't let me do that from the DVD.
I'm stumped, any help would be REALLY greatly appreciated!
Some more useful info:
My main OS is Windows 7 Ultimate x64. My motherboard is ASUS M4N68T-M and my CPU is Athlon x3 435.
I'm using the onboard RAID in RAID 0 configuration (2 500GiB HDDs as one 1TiB drive).
I have several partitions on this drive, NTFS, FAT and FAT32 but the bulk of my data is in a one 500 GiB exFAT partition.
All of the 3 OSs are on NTFS partitions.
If I left out something important please be patient, it's very late at night here.
Thanks in advance,
OU
