I want to a clean instll of windows XP. I get into the boot menu
and can't move too selct boot from CDrom. The only way to get
"out" is to turn off my computer. How do I boot from cd then?
You have to change your BIOS boot order to put the CD drive before the
hard drive.
How to get into your BIOS depends, not on Windows, but on what
motherboard/BIOS you have. As a matter of fact, you have to access the
BIOS before Windows even starts to boot. One common way is to press
the Del key when you first power on, but that's not necessarily right
for your computer. Watch the screen carefully when you first boot;
there's often a message there telling you what to do. If not, check
your system documentation or check with your vendor.

Or just try the Del key. There's a good chance that's correct for you.
