I am using my Secondary system right now. I reformatted my system a while ago and i cant reinstall my OS. I am now trying to boot from a different CD(because the other disc doesn't have the CD key), which is Windows Office and it has the key, but when i put it in it says that the intel boot agent or whatever can't find anything, and my PC doesn't boot from CD, How can i make it boot from the CD? From what i know of the Windows Office discs are used, so i am not sure if thats the problem, i don't want to spend cash on an OS and it not being able to boot up. System specs are in ''System specs''
