I did an AVG update on my vista computer, and when I started up next day, it stayed in the windows loading screen forever.
When I try to start safe mode, it gets stuck on /DRIVERS/avgidsha.sys, so I am guessing the problem is AVG related.
I tried burning AVG Rescue discs, and Windows recovery discs, but none of them seems to work, I get the error, Boot From AHCI CD-ROM, error.
I opened BIOS, and changed boot sequence, I changed bootup with F8, but nothing helped.
I even tried to replace my disc drive.
