Okay, when the official Windows 7 RC came out, I wanted to try it, but I wasn't sure how things would work so I kept my original XP and put Windows 7 on a second partition on the hard disk. After trying windows 7 I decided I liked it, and after transfering my files I decided I didn't need windows xp anymore, so I deleted that partition, but after that, every time I tried to boot I would get the message "ntldr is missing" and it wouldn't boot. So I copied all my files to a second computer, and from there installed windows 7 again, and now with windows 7 taking up the whole drive, my computer won't even boot to it. I don't have a dvd burner, so each time I installed windows 7 i just extracted the contents of the dvd iso to the drive and ran the "setup.exe" and it installed fine... but now it seems that the only way I can boot to the drive is if I have it in a computer running windows xp. How can I fix this problem? I would like to run Windows 7, and JUST Windows 7, but my computer doesn't seem to want to let me. I read that windows 7 doesn't use NTLDR to boot so could that be the problem?
