After googling the internet, I've compiled a solutions on how to remove the GRUB from Windows.

Boot your systems using a Windows 9x/ME boot disk and run the following command.
The MBR will be rewritten and GRUB will be uninstalled.
For Windows XP
In Windows XP, you can uninstall GRUB as follows:
Boot from the Windows XP CD and press the "R" key during the setup in order to start the Recovery Console. Select your Windows XP installation from the list and enter the administrator password. At the input prompt, enter the command "FIXMBR" and confirm the query with "y". The MBR will be rewritten and GRUB will be uninstalled. Press "exit" to reboot the computer.
