Ok I have Red Hat 8 on 1 harddrive and XP on another. I want to duel boot without having to reinstall XP. Is this possible? Also I am wanting to try other Linux distros with this same setup.
Sure, install Lilo or grub to the MBR and configure it. You might have lilo installed already. In Slackware the config file for lilo is located at /etc/lilo.conf.
