I've got a problem. I know dual booting with Ubuntu and XP is relatively easy to set up during the installation.
My problem is that XP and Ubuntu are already installed and fully functional. They are installed on different hard-drives. The person using them opens his box prior to every boot and unplugs the cable from one hard drive and switches it to another when he wants to change operating systems.
How to I go about correcting this without him losing all his data?
