OEM Retail disc not compatible after SP1 upgrade?
Posted 14 January 2012 - 05:56 PM
So I've got a copy of win 7 ultimate x64 OEM that I installed a while ago and it's pre-SP1. Everything has been fine up until last night when I installed some windows updates, but didn't feel like rebooting so I delayed it to do some gaming (mistake 1). While playing one of my games the system blue screened and forced a reboot. After rebooting I got a error message that said "BOOTMGR not found" or something along those lines. I don't have any recent backups (mistake 2), and I don't have any recovery discs besides the OEM install disc (mistake 3). The OS is installed to a SSD, and even though my motherboard is UEFI compatible, due to some technical issues I installed the OS in BIOS mode. When I boot into the OEM disc and select the repair option I get an error message that says essentially that the disc isn't compatible with the installed version of Windows. I suspect the issue is that the installed version was upgraded post install to SP1 while the disc is pre-SP1. I've also tried various combinations of booting the disc in BIOS/UEFI mode but the result is always the same. I've got a computer running Windows 7 Professional x64, a computer running OS X, and a Arch Linux laptop available to me in addition to my currently not functioning Windows 7 Ultimate x64 computer. Can anyone think of or recommend a utility or process I can follow to fix the boot config on my toasted system? I don't believe the issue is the hardware as the install disc and BIOS both seem to have no trouble detecting the HDs, rather I think it's just a corrupted boot config file (BCD?). What would be ideal is if someone could point me to an iso that could at least get me to a recovery console, but anything that's better than the full re-install I'm currently looking at I'll gladly take.
