First let me apologize if this isn't the proper place for this, and if so can someone point me to where it would be better to post this.

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.

If you boot from the Recovery DVD and press SHIFT-F10 can you get to the command prompt? If so try c:windowssystem32bcdboot.exe c:Windows /s c: (where C:Windows is your windows sp1 installed drive).

Thank you! That worked perfectly. I thought there was a way to get to a command prompt from the install DVD, but everything I could find through google always started by having you go through the repair link which of course was failing for me. Hopefully from here I should be able to follow some of the other guides and info I found to rebuild the BCD and whatever other problems there are.
