Unless there is another setting in the bios I don't know about, it's gotta be something wrong with my computer. I have attempted to install XP many times. The cd rom drive is always the first boot device when I try to install XP. But it never starts. When my friend needed to install his OS, I wanted to try out my copy of XP on his computer just because I knew that XP is supposed to be bootable from the CD. It worked fine... Just doesn't work for me.
