I have recently taken in a computer from a friend. He had a bad virus. I gave him my thumb drive to be able to back up some of his files so that I can reformat and restore Windows, as there was no way to remove this virus... however when he put the thumb drive in, the virus destroyed a system32 file and Windows wouldn't startup anymore. Since then I've tried installing Windows XP onto his machine... but everytime during the system setup phase where it copies the system files to the hard drive, I get random messages about "Cannot copy file..." and it gives me options to contiue without copying file, cancel setup, or retry the file... again, this is on the blue screen portion of setup, and all the messages that give you those options take up the whole screen. I contacted Dell for technical support, ultimately after spending maybe... 3 hours on the phone with them, the technician wanted me to go to bootdisk.com and get a bootable iso (really couldn't find one), and he said we would use the "debug" command with like 7 steps to remove everything from the hard drive. Downloaded a utility from Seagate to do a low level format. After doing the quick format, I was able to install windows, but windows update failed twice while it was running, and then after it updated I got a BSOD and had to reformat again... the long 6 hour low level format that writes all 0's to the drive didn't work either, windows xp failed to install... also tried my disk, as well as his, and both would fail at different parts copying files. Also, dell's diagnostics failed on the memory ONCE but I could not re-create it... sorry for the rant, just wanted to give you all the details. Any ideas?
