You can't do this from XP. You can't merge partitions in XP. You will need
3rd party software. When you get rid of the Vista bootloader you will in all
likelihood also corrupt or overwrite GRUB. You have a very complicated
setup. Trying to figure out exactly how to do this without being there is a
guess at best. In general it would go something like this. Boot from an XP
CD to the recovery console and run the following commands: FIXMBR, FIXBOOT
This will probably mess up GRUB but it should create a single boot to XP.
You'll now have to boot from your Linux CD and fix GRUB. Once you've got the
multi boot running with GRUB you can use a partition editing program to
delete the Vista partition and possibly merge it with the XP partition. I
say possibly because they may not be adjacent to one another. It is very
probable that in doing all this you will cause some problems with or another
of the remaining OS'.
