Tertiary Install of Windows over Ubuntu Linux, need advice!
Ok, so as of right now I have two OS installs on my laptop. I have an install of Windows Vista Business x64 and an install of Ubuntu Hardy Heron 7.04. This has been working great for as of now, but recently I picked up a MIDI Controller to use in Ableton 7, unfortunately there are no 64 bit drivers for the controller. This means I am going to need a 32 bit OS. I need to install XP or Vista x86 over the top of these installs without formatting. I spent a great deal of time getting Vista x64 and Hardy x64 getting properly configured on this laptop and I do not care to do it again, so formatting these partitions is not an option. I would also like to preserve the MBR. So my question is how would I go about putting a third OS install on this machine without wiping GRUB's master boot record? I know some of you gurus know a way to do this, so any advice would be more than welcome :)
