Ok, so I'm installing my new hard drive on my hp desktop because mines failing atm. I only backed up needed files on a external hard drive so I can have a fresh new hard drive. The new hard drive is the same as the old one. So I replaced it, booted it up, the BIOS recognizes it, but when I try to install windows 7 with the install disk. I get a bootmgr is missing. I couldn't find anything to help, but thats the error get whenever I try anything. Anyone have any idea what the issue is?
Bootmgr is the program that checks for what OS you have installed(so if you had a win7 bootmgr, it checks your harddrive for win7 and the older versions of windows for boot options). Can I ask one question, is the disk you are using to install windows 7 a upgrade copy or a full retail licence.
I am also assuming that that new hard drive is the only hard drive that is plugged in at the moment.
if that is what you purchased, no thats a retail copy(which is good in the long run, if you ever want to change motherboards as well). are you sure that the new hard drive is wiped clean entirely, and theres no traces of data on it? Is the dvd drive on priority to boot inside the bios?
it should be on ACHI unless you were doing a raid setup. boot order before installing windows should be Optical Drive first. after you install windows, the first boot order should be the Drive with the OS on
my i offer some odd advice, unplug the sata cable from the mobo side connecting to the disk drive and hard drive, and use it on another sata port. there's that tiny chance that one of them is working wrong.
