I have a Compaq desktop that's running Vista. It belongs to a friend of mine when I got it, it would not boot to the desktop. So someone told me to take the harddrive out of the Compaq put it in a working computer to reformat it. There were 2 partions on the hard drive C drive and a recovery partion. I reformatted the C drive using the disk management feature and I did nothing to the recovery partion. So the C drive is now empty. When I try to boot from the cd/dvd drive to reninstall the operating system is won't let me it gives me the "Bootmgr is missing press alt+ctrl+del to restart. I don't know what else to do.
