I'm working on a win7 x64, and had to remove one of my hard drives recently. After removing it I discovered that the boot files were installed into that drive, and the system won't load. I tried many solutions listed in the forums (such as using the startup repair tool with 3 reboots, using bootrec /rebuildbcd, etc) but to no avail.

Right now I'm trying to rewrite my bcd, but bootrec /rebuildbcd returns 0 available operating system installed. What should I do?
