Every time I turn on my gaming PC now, I get the following error.

"
Loading Operating System...

BOOTMGR IS MISSING
Press Ctrl + Alt + Del to restart

Tried reparing windows from my Windows 7 CD, which didn't work.

I might try installing Windows on the Other drive, and recover what I want to keep desparately onto a memory stick or something and then formatting and re-installing.

But tbh, I'd like to be able to fix this without a complete re-install, ideas?
