I bought a rebuilt computer a year ago, used it once, shut it off and now it won't boot. I have done a lot of searching and for the last 2 days feel like I am getting somewhere, but now I have hit a dead end. I have made 3 different rescue cds and 2 found nothing, but with the last one, avira antivirus rescue cd, the results came back with 3 alerts.... [unexpected end of file]/media/devices/sda2/windows/system32/catroot2/edb00428.log and 2 others ending 00429.log and 0042A.log My question is how to I get rid of what ever is causing this so i can get into windows. After it wouldn't boot, I contacted the person I had bought it from and he said that there wasn't any virus protection at all on the computer. That would have been nice to know before I shut it off. I feel like a dummy because I didn't know this before. Before I did the rescue cds, I was in the "infinite startup repair loop" and the first time, I got corrupt registry as the root cause, then I did some research on that and used cmd to copy and I think I fixed that cause now I get a baddriver as a root cause. Please, can anyone help?
