Brief history. I have a copy of xp pro (lost my origional awhile back but was smart enough to burn it). Installed it on a clean partition on a hard drive that already had 98SE installed. First 2 attempts failed to install and said "usbohci.sys is corrupted" 3rd attempt (no changes made btw) and it said "halsomething or another is missing or corrupt". 4th attempt (still no changes) it installed just fine. So I put the cd in the jewel case and put it in a drawer. Fast forward a few months to last night. My dad calls and said his computer is stuck. So I go over and determine the hd is toast. It makes funny clicking sounds and smells smokey I get him a new hd today (60g maxtor) and decided to install xp pro vs 98SE. I expected to have a problem like I did when I installed it on my comp. However, after a dozen install attempts I gave up. Does anyone know a way to fix the "usbohci.sys is corrupted" issue? I don't have the origional xp pro cd because it's lost (probably thrown away by accident during one of the cleaning sprees).
