I would like to install Fedora 9 on an external 2.5" hard disk I have lying around, for use with my laptop. While the laptop supports booting from USB pendrives, the hard disk appears to be incompatible for booting.
I would like to be able to boot the Fedora installation by just plugging the USB hard disk in, and dropping a CD in the drive then powering on the laptop. I don't want to have to touch the internal hard disk at all.
Can anyone point me to a guide, or give me a few pointers?
