Windows 7: No Boot Device detected, but hard drive still works

No Boot Device detected, but hard drive still works

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?

OS: Windows 7 Ultimate x64
Motherboard: Gigabyte GA-Z77X-UD3H
Harddrive: Seagate Barracuda 1TB 7200RPM 64MB SATA 6Gbps

Thanks

Troubleshooting Windows 7 Failure to Boot

Partition - Mark as Active

Use method 2 of the 2nd tutorial to mark your windows partition active, then run startup repair up to 3x with your W7 disc. That should get you booting again.


Your boot files were on the XP drive, when it died it took your boot files with it.
