Alright. I'm going to try to remove the hard drive, so I can either format it from another computer, or just remove enough files that it'll run the startup repair. I'll post back if it works.
EDIT: I got the drive out, but I don't have an adapter. To clarify from earlier, here's what I would do with this plan:
Remove the drive.
Connect it to the laptop of someone who has 8.1 installed (it came preinstalled). One with 8 is also available if necessary, since that is what my computer shipped with.
I would then use this connection to format the hard drive from that laptop, instead of from mine. from what I read this would completely blank the hard drive, removing everything, including the OS. (I'm not entirely sure if that would be the case, since this computer shipped to me with windows 8 already installed. A method that would restore everything, OS included to factory settings instead of destroying it outright would also work, but this is the first time I've tried to do this, and I don't know if it would work.)
Assuming the above did not leave an OS, I would then use an image(or something, I'm not entirely clear on what I would do at this point) of the windows edition in whichever of the other computers I used to reinstall windows to my hard drive. If there is no way to use the other laptops, my college gives out free editions of Windows 7 to students, which would be an acceptable outcome at this point.
Hopefully that clears it up, I was kind of vague earlier. Thanks!
