BOOTMGR is missing and no OS

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!??

With the DVD in the tray, power on, then when you see "press any key to boot from CD/DVD", press a key.
(just once.)
During the install process, the PC will reboot a couple of times, and you'll see the message again.
Don't "press any key.." on the reboots. That would start from the very beginning over and over in an infinite loop.
