I needed to reinstall windows on my work laptop as it was getting a bit sketchy and unreliable in that undefinable way, so I took the opportunity to repartition the disk and set it up as a dual boot machine, with ubuntu. I created a primary 15gb partition for windows and installed win xp in the usual way, then used the partitioning tools in ubuntu to create a 15gb partition for data (Ext3 to be shared between windows and linux, by installing these ext3 drivers in windows), and a 6gb partion for the ubuntu install. It all went fine, but the wireless card isn't recognised by ubuntu. I've looked into it - apparently I can get it working using some windows driver voodoo that goes by the name of ndiswrapper. I haven't tested how/if ubuntu handles sleep and dual monitors yet, but will do at some point.
