OK, I'm on my Mac right now...
I installed pretty much a full installation of Red Hat. It restarted after it finished, and now it just says "GRUB" on a black DOS-esque screen. It doesn't boot, it doesn't do anything. Putting in the boot disk did the trick, but only gets me to Red Hat...I can't get into any of my other OSes! HELP!
Thanks
BTW: I've installed Red Hat before, and never had problems.
