    Installed Ubuntu on external drive boot problems

    I installed ubuntu on an external drive to try it out. It has worked great and I've been impressed by it stability and polish. When I boot the laptop, I use grub to pick either ubuntu or windows xp to boot from. The problem I run into is when I take the laptop and the external hard drive is not connected, I get an Error 17 and can't boot into anything, as no operating systems appear to boot into. What I was hoping for originally was to let it boot into Windows XP when the hard drive was unplugged and into either ubuntu or windows when the hard drive was plugged in. Is this feasible and how would I go about doing it? If I can't do that, can I install ubuntu again with the external hard drive unplugged (from the CD) and partition my internal hard drive and will this straighten out grub or will I have to leave the external hard drive plugged in forever? I played a little with linspire (no comparison to ubuntu) but really understand little of working in terminal so please assume no knowledge on my part when answering. Thanks for all the help.

    Grub gor got probably installed half in your internal drive and half on the external.

    Re: Installed Ubuntu on external drive boot problems

    Thanks Pumalite. I think your right that grub is installed partially on both hard drives. The links you gave me are great. First thing I did was download the supergrub iso disc image and make a CD out of it. Loaded it in the laptop and I can now get to windows when the external drive is not connected. Great solution till I figure out a more permanent answer after reading through the two links. Thanks again.
