I used your “Ubuntu: Old Computer, New Life” guide and created the disc as instructed on an old Dell Precision 360 Desktop with Windows XP Pro SP2. I then booted the disc and it says boot error and prompts me to strike F1 to retry. This does not work and now when I change the boot sequence back to normal it says the system requires a password that I never setup and now I can’t do anything with that computer.
I am using another computer to ask this question. Can you help me get the Dell booted up at all or even better help me continue with the Ubuntu installation?
