How to Remove Grub Boot Manager
- 1). Insert a blank CD or floppy disc into your computer and exit out of any auto-play options that appear on your screen. Click on "Start > My Computer." Find the blank disc you inserted under the words "Devices with removable storage."
- 2). Click your disc with the right mouse button and select "Format" from the menu that appears. Check mark the box next to the words "Create an MS-DOS startup disc." Click the button labeled "Start" at the bottom of the format window.
- 3). Wait for Windows to create your startup disc. It will say "Format complete" when it is done. Turn off your computer, leaving the disc inside, then turn it back on. Press the space bar rapidly until your computer starts beeping and the message "Press any key to book from disc" appears. At that point, press any key on the keyboard and it will boot using your MS-DOS startup disc.
- 4). When MS-DOS finishes booting it will display "A:\". Type "fdisk /mbr" and press "Enter." This will remove the GRUB boot manager and replace it with a Windows boot loader. Eject your MS-DOS startup disc and restart your computer.
