bootmgr is missing” in Windows 7

The dreaded message “bootmgr is missing” still exists today, but luckily there are some easy solutions.

chkdsk C:\ /f /r

This might take some time, depending on the size of your hard drive, but it is necessary to verify that there are no corrupted files on your disk.
