Man, it feels weird to make new threads instead of posting in QTQT. Ah well.
So, currently my laptop dual-boots Ubuntu and Windows XP. Ubuntu came with the nifty Grub boot manager to let me choose which one to boot on startup.
Problem is, I always use Windows and I'm running low on disk space - so Ubuntu is getting the axe. But I know I can't just remove the partition it's installed on, because the computer will look for that Grub boot manager on startup, and it won't be there any more. Is there a non-painful way to do this?
You need to go into the BIOS and set the CD to be the first device to boot, put the hard drive second. Do you have Windows installed already? If so, boot from the CD, enter the recovery console (press R when it asks you whether you want to install windows etc.) When you're at the console, type:
fixmbr
and that will remove GRUB from your system.
If you don't have Windows installed, GRUB will be overwritten as part of the installation.
There are also a few other methods descriped on that source as well.
