|You cannot access a Linux partition from XP, BUT you can use an NTSF partition to save all or some of your data to that will be accessible from XP, Vista and Windows 7. You may need to search out opensource programs that will allow you to open some of them though. Openoffice.org is one case where you can get a free office suite that will run on XP and has an equivalent in Linux and can also open MS Office files as well.|
For more information, post in Linux forum and Google Opensource.
You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
