Well to start off, my father is no idiot when it comes to computers, but this is no error we could not fix... My Story: (Pre-Windows 7) It started off when my little brother had installed an Ubuntu downloader the Windows XP called Wubi. The installer basically sets up a dual boot with Windows XP and Ubuntu. Everything went smoothly but every time I would start up Ubuntu, it would give me a couple weird error like messages then try a different terminal command. (Repeated several times) Then loaded some setup and Ubuntu would further run smoothly. Installing Windows 7 I decided to try Windows 7 out, so my dad had prepared a partition for Windows 7 and installed it using a CD installer. It worked, but then I could not run Windows XP. Therefore, I could not edit the partition or uninstall Wubi (Ubuntu). My dad and little brother tried everything they could possibly do to recover the rest of my files (most of my files are on a flash drive) but with no luck. Yes, even tried to use the Windows XP repair disk and search for the files through Ubuntu. Erased the Hard-drive With nowhere else to turn, my dad erased the hard-drive and started me up with windows 7. After testing thoroughly, I realized a game I absolutely love (The Sims 2 with a whole 7 expansion packs) will work only with a DirectX 9.0c compatible drive (I had DirectX 11 on Windows 7 and it worked on XP as well). Windows 7 and Windows XP Dual Boot The final decision was to set up a partition and install Windows XP (Service Pack 3). Once Windows XP was installed on the right partition, it reboot of course, then the computer refused to show the boot menu. It literally shows:Code: | This bothers me. I can not boot on XP or 7. I tried to repair the Windows XP partition, even tried to install it on top of the Windows XP partition, even tried to boot with multiple computer boot things I found in the computer's stat up, but still nothing. What I was thinking, was that we just Wipe the hard drive and start over with Windows XP, but my dad thinks it can't be done. He thinks that the Windows XP boot manager is not compatible with the Windows 7 one... Any help is appreciated.
