Yay! This is actually an extremely simple fix.
So, on the recovery drive, there is a "bootmgr" file. Your drive requires the same file, but in all CAPS. So, put the drive in another PC so you can work on it. Copy the "bootmgr" file from the recovery partition to the main drive. Then rename the "bootmgr" file to "the" then rename it again to "BOOTMGR" (Windows won't allow you to rename a file where you only capitalize letters, hence changing to "the" first).
Boot the PC
Or if you are still booting from a DOS usb, you can issue these command against the machine
Once in DOS, find out
which drive is the recovery drive (we'll call it r: in this demo)
which drive is the root drive (we'll call it c: in this demo)
xcopy bootmgr c: (if xcopy doesn't work, just use 'copy' instead)
ren bootmgr the
ren the BOOTMGR
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
