How to Remove Grub Boot Manager

If you have a dual-boot setup (two operating systems in one computer) using Windows and Linux and Linux was installed last, Linux put a boot manager on your computer for choosing which system to boot into. The boot manager is known as \"GRUB\" and is used in most Linux/Windows dual-boot situations. If you'd like to restore your Windows boot manager, you can do this without needing a degree in computer science.

Step

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.\"

Step

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.

Step

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.

Step

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.
