Could somebody explain how to install windows XP in virtual box for me in detail. Im currently dual booting but i only do this for itunes, cuz i have an iphone and i dont want to jailbreak it... anyway i want to run windows and itunes in a virtual machine but i dont know anything about stuff like that. Also i was wondering if programs (itunes) installed in the virtual machine will stay installed when i run it again, and if i test this out and dont like it can i reallocate the hard drive space i used for the VM to ubuntu.
