holy crap, you guys were right.
though the boot sequence was correct, the hard drive priority setting was set to my 160gb drive that i used for media/download storage. i switched it to my old 80gb, and it worked fine. oh man, and this whole time i was worried about a dead drive. SOOOO not the case.
now only if i hadn't formatted and forgot to backup my doom save files.
oh well, gettin that 36gb raptor. who wants this one? 60 bucks shipped!
