I originally had been running windows XP on my desktop. About a month ago, I bought a new hard drive and installed Windows 7 Ultimate x64 on it. For the last month, I have been able to dual boot between Windows 7 and XP just fine.
When I tried to boot up my machine this morning, my computer no longer boots and have the following message on screen:
"Reboot and Select proper Boot Device or Insert Boot Media in selected Boot device and press a key"
I checked my BIOS and found that only my new hard drive and CD ROM are detected. I imagined that my old hard drive with Windows XP on it finally died. So I disconnected the old drive, but I am still getting the same issue. I have tried changing the boot order. I also tried booting with the Windows 7 setup CD and tried the repair tools. None of them recognizes the Windows 7 installed on my new hard drive. I started command prompt and was still able to see the contents of the new hard drive, with its WINDOWS directory and all my data/installed programs, so I believe the new hard drive still works. Is there anyway for me to fix this without having to reinstall Windows 7 again and lose all the data/programs I have? Does this have something to do with my XP not being bootable anymore?
