Windows 7 not booting from SSD, install not listed on repair disk

Randomly, my computer is no longer able to boot from my OCZ Agility 3 SSD. By randomly, I mean it was working just fine this morning, but no longer. I can't remember if I changed or updated anything.

Well I then went and inserted the Windows 7 repair disk. A list pops up saying to select my OS, but nothing is listed. I selected load drivers, and I'm able to navigate to the ssd successfully and view all of the files. I even plugged it in to the computer I am using now and was able to back up the more important documents in case I will need to do a reinstall. (I would rather not though). The repair utility doesn't fix the problem, and I navigated this forum and many others trying to find similar problems to mine. I'm sorry if I missed a thread very similar to this, I just need help with my problem. I'm also sorry if I posted this in the wrong thread or sub-category, I'm somewhat new to this forum. All I know is that this is the place to be for anything PC related.

I don't know what information to give, so I will just post my system specs.

Windows 7 Ultimate 64-bit
AMD Phenom II X4 965
Galaxy GeForce GTX 460
16 GBs Corsair RAM

I do have two other hard drives on the system that I use for general programs and another for raw video storage. They are disconnected now, so I don't see how they would affect the problem.

I would prefer to solve this problem without re-doing my entire OS, but I will understand if there is no other way out. Any help will be greatly appreciated, and if you need any more information, I'll post what you need gladly.
