Have you already gone into your BIOS and adjusted your boot priority for the drive you want it to boot from?

Hi

It looks like the boot files for both the windows installations are on one hard drive which is the one you have removed

It maybe fixable if you boot off the correct widows DVD or USB or repair disks

It helps if only 1 hard disk in place when installing windows so the boot partition is on correct drive

(In a win 8 section asking about win 7 problems ?)
Are you talking about sata power or data cable ?

Sata to molex power adapter or splitter
cables easy fixes power problem

You had both drives connected when you installed. The boot info (System Reserved partition) lives on the wrong drive.
Remove that drive, and no boot for you.

mbarnes68 and USARet you were both correct about the boot file issue, best answer went to mbarnes, since he solved it first although, I do thank you both for the awesome info. I loaded up my Win 7 install CD and did a repair on the installation and presto, it fixed the issue. I'll remember from now on to only leave connected the drive I wish to install windows on.
