Now a day it’s quite common for having Windows and Linux installed on the same machine.
Every time when you boot your PC, the Linux boot loader GRUB (Grand Unified Boot-loader) comes up with the available operating systems that you can boot with.
Now what if you want to completely remove Linux form your system and continue using only Windows..? Simply removing the Linux partition will not solve the problem. Since the GRUB will be installed in the MBR (Master Boot Record) by default, you can not directly boot in to windows.
If you have ever faced this situation or if you want to remove Linux from your system completely then here is how you can do it. Firstly grab your bootable Windows XP CD and boot from it. When it asks for whether you want to go in to Recovery mode, press ‘R’ to enter in to Recovery mode. Enter administrator password and login to the system with Recovery mode. Now enter the following command at the DOS prompt and hit Enter.
C:\fixmbr
Assuming that ‘C:\’ is your Command Prompt. A warning message pops up stating that you are altering the MBR and this may harm the system permanently. Press ‘Y’ to accept. Now type Exit to quit form the recovery mode.
Now onwards you can directly boot into Windows without the intervention of GRUB.
