Probably under " config " look for boot options . Select , depending how it is written , Boot from CD Rom , you may have to select it from a box that will open on the right or you might have to use the up and down arrow keys to move it to the top of the pile . Exit from the bios ( esc. then F10 commonly ) then it will reboot with the CD first .
Have you been into BIOS???? not windows. to enter you have to press ether a key or key's. Try the Del key as the computer boots, arrows keys let you move up down and side to side, enter key will open a page, Escape key will close a page. Look for Boot Order page. Save before exit
Just a thought but my BIOS identifies a difference between CDROM and DVDRAM drives.
Found this out when I tried to repair windows some time ago - because the BIOS was set to boot from CDROM it just went straight to the hard drive (being next in line). It was only when I scrolled down the list of options for first boot device that I found the alternative - as I have a DVDRAM instead of a CDROM it made sense, but I had just assumed it would see the DVDRAM as any CDROM - wrong!
So if you have something that is more than a CDROM drive check the list of options to see if there is something more relavent, and select that.
