you have to make sure youre computer is set to boot from cdrom first,
Youll need to go into the BIOS, when the screen comes on start pressing delete, keep pressing until the bios comes up, or untill you see it booting into windows, if it doesnt bring up the bios, reboot again and try it with F1, F2, and F8. One of those will bring you to the BIOS
once in there you need to look for the Boot Sequence, and you need to change CDROM to first boot device, then sve it and exit
this time it will do it, but YOU HAVE TO KEEP YOUR EYES ON THE BOTTOM OF THE SCREEN! It will only say it for about 3 seconds and then boot into windows. AS SOON as you see it telling you to press a key, hit something. Then youll be in the right place.
