Mac the Knife
Just compare the two operations:
(1) Installing LILO/GRUB
Automatic as part of install process, one screen, one simple answer (unless you want to install GRUB on the 2nd hard disc as I did and modify the XP loader to load it, then it's a bucket of problems)
(2) Removing LILO/GRUB
To get rid of the Linux bootloader (GRUB or LILO).
Boot to your Windows XP CD and select the first Repair option.
This will put you into the Recovery Console.
You will need the Administrators password.
Run FixMBR (just type "fixmbr" - without the parentheses - and press the ENTER key).
This replaces the Linux boot loader with the Windows one.
Take the Windows CD out and reboot, you'll come up in Windows
Easy when you've done it a few times, but for the first time user add "Looking at Microsoft support web site for details of how to reinstall MBR" and "Noticing the warning that doing this may cause further problems"
To me, if it installs easily it should deinstall just as easily, but then I only design software for a living so what do I know about this?
