Windows XP + ubuntu Linux
(This will only work with the retail version of XP)
:Install XP:
Make two partitions, one for windows XP, and one for file transfer, leave space for Linux.
(example: 160GB HDD: 100GB Windows XP [NTFS], 10GB [FAT32], 50GB Linux [EXT3])
For the FAT32 partition use partition magic.
Once XP is installed we can go on to the Linux install.
:installing ubuntu:
Once you get to the partition editer select manualy edit partition table.
Make a EXT3 partition to install ubuntu on and set as active.
When it asks if it wants to install the GRUB boot loader select yes.
Finish the install.
