I can't use a DVD to install Windows 7 so I had to install it from inside my existing 7 installation on a separate hard drive. That went smoothly onto my new HDD. The problem is that when I remove the old hard drive with the old 7 install on, the new install will not boot. I believe it has something to do with thr boot manager being on the other HDD. Can anyone point me in the right direction of some good instructions to solve my problem?
