Re: adding XP to a linux dual boot system
As you already have mint/ubuntu installed things will be a little bit more difficult as windows prefers the first partition of the first hard drive. Need to know more information such as how many hard drives you have, present partitions etc as windows will not boot from within a logical partition. Post the output of Suspect you may have to shift some partitions around with gparted, install windows and then reinstall grub, but others may know of an easier way.
