Hey. I really need some help! Im a bit of a newbie but i just brought a computer from a guy who formatted the hard drive (apparently a few times) before i brought it. I have the Windows 7 Prof disk and so i thought i could load it myself. So there is no OS and the hard drive is completly blank. When i start the computer it says: "boot from CD/DVD" then "BOOTMGR is missing" I have no idea how to get it to work!? Can anyone help!?? Cheers!
