Triple Boot MacBook: Leopard, Ubuntu and XP
Sep 12 2008 - By George Webster
Triple booting the MacBook has vastly improved since Tiger. I literally brought home a new mac book, installed a 320 Gig harddrive, maxed out the ram (4gigs) and installed Leopard, used bootcamp to install XP and added a partition to the main Leopard partition while it was booted and installed Ubuntu.
Simple and painless... all is well with the cosmos.
This post is pretty straightforward the only thing i did different was to install XP instead of Vista (for reasons i hope are obvious!).
Configuring Ubuntu Hardy Heron on the macbook took a few tweeks, but they are outlined well here.
