Problems Choosing Which HDD to Boot From

After my old computer's motherboard bit the dust, I moved that hard drive onto a new PC. This is where I'm running into major issues, or rather, a major issue that is giving me a headache.

When I tried to make that hard drive the primary one, Windows wouldn't run; it just kept taking me to System Repair. I know that Windows 7 is on there.

This hard drive, which is a data drive right now, is where all my programs and files are, and the hard drive that came with this PC doesn't have nearly enough space for all of it (new hard drive is only 80 GB, the one I'm trying to get to boot is 500 GB, of which 220 GB is filled). I don't have a Windows disk (that and I had to sacrifice my DVD drive to get the second hard drive connected. Is there a way of fixing this issue?

Thank you, and also, hello, everyone. :)

You can't easily/simply move a hard drive from one computer over to another (with dissimilar chipsets/cpus/drivers/GPU/integrated MB components, etc., and simply expect to boot and run Windows from it....

If you can access your data and files, back up what you need from it, delete the partitions/repartition as you desire, and do a clean install....you will thank yourself later.

If this hard drive had a Windows OEM license and installation, you should expect problems when putting it in a "new PC".

The license won't be valid on this new PC.

Or do you have a non-OEM license?

Thanks a lot. I can still access all of my files. But issues I'm having with running games on that Hard drive is probably an issue for a different board. That was most of the reason why I think I needed to be able to make my old hard drive bootable.
