---------------------------------Uninstall Grub from the Master Boot Record (Help) -----------

This option lets you uninstall Grub from the Master Boot Record.

But this is not quite an accurate thing to say.

What actually happens is we are overwriting the MBR with another 
bootloader's IPL code that will, for example, point to  Windows XP
where the NTLDR bootloader will take over.

So we have to choose the operating system that we had installed before
installing Grub.
