i have 12.04 saved on my external HDD. it was from a netbook and ran Windows xp pro before i dropped it on it's head. the drive works and i am using it to back up my whatnot. what i can't figure out is if it must be installed on the external drive first before i can install it on my laptop and be rid of the curse of Windows for ever! i have also put 12.04 on an 8gig SD chip but it doesn't show up in the boot options during startup. i tried to access the ext HDD to run the boot up but it told me some piece was missing.ARGH!
