Many XP systems will not boot from a CD unless we go into the BIOS and change the boot order.
You didn't state what make or model, so we don't know what method you should use to enter the BIOS. The BIOS, (Basic Input/Output System), is the first screens that display whenever you turn on the computer. To enter the BIOS you need to press a particular key as soon as the BIOS displays, (too late and you miss it), and the keys are Esc, Del, F12, F11, or some other key or combination of keys. Which key(s) to press is often displayed on the screen.
Once you are in the BIOS look for something like the Boot tab, or Advanced BIOS features. Then look for Boot Device Priority or for First, Second and Third Boot Device. Make sure your CD/DVD device is listed before the hard disk.

I've been having a problem for a few months now of not being able to Boot XP properly, and I'm taken to the "We apologize for the inconvenience, but Windows did not start successfully" with the options for safe mode and whatnot. When I choose any option I get the XP load screen for about three seconds, sometimes followed by a blue screen with text for about one second.
So now I just want to start clean because aside from this problem there is so much unwanted material on the computer and I want a fresh start, I know that last part sounds bad but it's not, but to each his own.
Anyway I put the disc in and i restart the computer, unfortunately I'm not getting the screen that allows me to start the installation.
