Hey guys! So I just finished building up my PC, everything is in place. I start it up annnnnnd the USB keyboard isn't working. It's the same keyboard that worked fine with my previous PC (I don't really have any other PC right now to test if it still works elsewhere) and the USB ports seem to be fine. When I plug my phone in them, I get power.

Without the keyboard I really can't do anything. Can't access the BIOS. Also, when I unplug the keyboard it goes to a different screen and I get a "BOOTMGR is missing" message. It's as if the PC was trying to boot from the keyboard instead of the optic drive where the windows CD is.

Any idea what's the deal here? I tried to find another keyboard but I don't have one at hand for now.

Well, it's kind of a catch-22 without the ability to access BIOS, but how do you know your new system is set to allow your keyboard to function through emulation mode? Without that, working or not, your keyboard isn't going to get you very far without a proper operating system and drivers.

Barring any other solution, perhaps you can unplug all SATA data cables to hard disks, but leave the power to them, unplug all USB devices, and leave only your optical drive plugged in fully, and see if you can boot at least with that minimal configuration? If you can boot into the Windows Preinstallation Environment, you can likely plug your SATA data cable back in to your primary boot drive and your mouse, and see if the installation can detect the new hardware and work with it then. If you can get at least a minimum going, you may be able to get past the emulation problem until you can get your hands on a keyboard that will get you into BIOS.

Yeah I was able to boot windows using a thumb drive but got into a dead end when it asked me to enter a user name. This weekend I'll have access to a PS2 keyboard so I'm hoping that this will let me access the bios. At least the mouse worked fine using USB ports. Maybe it's really just my keyboard that blew up with my last PC (which died on me last weekend).

If your mouse is working, it's likely due to a generic driver the Windows installation has loaded, not BIOS. Perhaps try with the keyboard unplugged, up until the point the Windows setup is actually loading, then plug the keyboard in, to prevent BIOS trying to do anything with the keyboard, and perhaps the Windows installation may catch the keyboard and load up a generic driver for it.
