View Full Version : [SOLVED] Uninstall/reinstall without password; cannot boot by CD, USB

When my school upgraded the cluster, they handed out the old computers for free. So I've got a few boxes (Shuttle XPC SN21G5 (http://global.shuttle.com/news/productsSpec?productId=88)) with Ubuntu installed, but locked up with an unknown password. I want to just wipe it and do a clean install.

Problem is, there is no optical drive, I can't get it to boot with my Ubuntu USB flash drive (when the USB drive is plugged in, the computer prints "Boot Error"). Booting from the USB drive works properly on my computer. (The USB drive has Ubuntu 11.04 and the computer I'm trying to boot with it is several years old... that wouldn't be a problem, would it?)

Are there any levers I haven't thought of that I could use to wrest control away from the current Ubuntu installation? The boot screen doesn't give me any options (e.g. F10 for boot menu, etc.). Or do I just need to pull out the hard drive and plug it into another machine?

Thanks--I just assumed this wasn't possible for security reasons, but it worked and I changed the password.
