Ok my buddy bought a dell 4100 system. Has no cd's,software or anything like that. It had windows me on it. He wanted xp on it so I fdisked it and reformatted the hard drive and installed xp on the the drive using my pc because I could'nt get his to boot with cd or with bootdisk. (Note from dell some systems will not boot from cd and the 4100 is one of them) When i tried to run xp setup from bootdisk it kept saying program wont run in dos mode blah blah. So I set up the drive with my pc and when He popped the drive back in his it said cannot find windows me. Its like the pc still thinks it has win me in it. And it says run fdisk. I did all that in the first place. What can I do to fix this. Not sure what model motherboard but I know it has the intel 815E chipset and sure it will run xp with no probs. Any help would be great Thanks!
