*Sigh*

Didn't I tell you to read a book on this a while ago? You need a boot app, like Lilo or grub or SOMETHING on the first sectors of the first HD telling the computer where everything is.....The MBR right now on that box has no idea any of those OSs exist, how did you expect it to boot them?

I'm not sure how you got all those installed and made them actually boot without knowing how it works....
