No, this is the error and fix page
for what I ran into. I actually saw that page while searching, though, and am considering trying it anyway, seeing as nothing else has worked at all.EDIT:
I've actually managed to boot my OS properly, though I don't know how. I just kept trying the same things over and over again, hoping I just missed something, and that it would work eventually. It did, so now I'm uninstalling every single language pack I have installed. It's about halfway done, and it's been running for two hours. EDIT 2:
Computer fixed, up and running again. Without Service Pack 1, since even after I managed to restore my computer and remove the offensive language packs, it refuses to install. Lame.
