All was well, then I installed Ubuntu Linux on a partition, I then removed Ubuntu and that was the start of a host of problems (MBR etc.) But here is the real problem, I tired of trying to rescue the XP SP3 and start over, I used my XP SP2 disc to bring up the service console, I ran fixmbr and chkdsk /r, both ran ok but did not bring back XP SP3. So I decided to just load my XP SP2, Windows said that there was an existing installation and would I like to repair it, so I hit the r key and enter, it loaded a ton of files then it rebooted and since then both CD and HD are tagged as disabled in BIOS. I have chosen default values in BIOS, verified boot orders, etc. many times, then I removed the CMOS battery for 24 hours, then I changed the BIOS jumper cables from 1-2 to 2-3 to 1-2 and still nothing, I disconnected the CD and HD and fired up the computer then hooked them back up, still nothing. Please give me an answer , I am stumped. Windows offer to repair the existing installation was the culrit in locking me out of the CD and HD. Thank You. PS I need XP to run legacy equipment, no other option. Leo
