I am building a computer and when I start it I get the error bootmgr is missing. Weird thing is that if I use that hard drive on my old computer it boots fine. When I tried to use os disk to restore my hard drive on the new computer, I can't because my keyboard won't work at that point and I can't press any key to continue. However, the keyboard works fine before so I can go into bios. Also i tried installing with a new hard drive but the new computer didnt regonize it after restarting. Not sure what to do next. Wondering if I need to update the bios or mobo is fried. Please help! Thanks.
