Triple boot pain

Today I went at a friend's place to help him set up a triple boot system. The PC is brand new and bleeding edge (it will be used primarily as a gaming device), but the guy was still curious about Linux. So I told him about Linux in general and offered to install Ubuntu. He agreed and we went on with the partitioning scheme.


The HDD had 500 GB and we agreed to set up the partitions as follows:

* primary partition - 50 GB - Vista Business x64
* primary partition - 50 GB - XP Professional x64
* primary partition - 25 GB - Kubuntu 8.04
* extended partition - ~375 GB
- 4 GB - Linux swap
- the rest - big storage partition

OK, so when all this was settled, I started the Vista install. It went OK, no troubles whatsoever. Then came Kubuntu - all went fine. I used GRUB in order to be able to choose between the two operation systems.
