Not posting for help but for future reference. (Note: moved SATA drive to slave on second box for all checkdisk, virus searches, and formats)
Got a nasty virus and tried to recover. Found the bugger but when I tried to remove it it got mad and destroyed Windows files. Tried run XP (SP2) setup to repair and try to save time not having to copy all my files again. Setup BSOD’d at “Starting Windows” and said check for viruses and run checkdisc. Did that several times with same thing.
Formatted drive. Tried instal with the same result at the same spot in setup. Fought this for biggest part of a work day.
Solution: In BIOS change HD to compatabilty (IDE, ATA) mode. (Refereced in my BIOS as RAID *** ATA. No idea why single drive is referenced as RAID now… I’m not that technically proficient, BUT this will allow install to continue if you have this problem. Also streamlined SP3 disc may not have this problem… I didn’t have one to try.
