I am trying to reset — or rather, install — a boot loader on my hard drive. I initially had a Linux distro installed, which I completely wiped out. Now, when I try to install Windows 7 from my USB, my machine says
Missing operating System
And when I don't boot with USB, it says
"bootmgr is missing"
So now I am wondering, how I can install a boot loader, so I can install Windows 7?
