I just fixed the problem.. I feel dumb for not trying it. Here's what I did if it helps anybody else on a problem like this or similar to it :
When you hold F8 at startup and get to the advanced boot options, go down and press enter on "Last known good configuration"
I was stupid... Did so much unnecessary stuff such as burning a recovery disk onto the flash drive, trying to get system repair to work, etc, etc.. It was all so simple. Thank god.
