When trying to start your Windows 7 based computer, if you get an error like : ‘BOOTMGR is missing’ then you can use the Startup Repair to fix the problems. Startup Repair is one of the options in the Windows 7 Recovery Environment. There are two ways you can boot into the Windows 7 Recovery Environment. Here is how :
- Change the BIOS settings in your computer so that your DVD drive is the first boot device and your hard disk is the second boot device. Place your Windows 7 DVD in the DVD drive and turn on your computer. When you see a message Press any key to boot from CD or DVD…., hit any key on your keyboard.
