(Definitely not those with Gnome or KDE, and not any 'buntu above 10.04 with 256MB!)
I agree. I'm running ubuntu 11.04 on a 512mb old desktop. It slows down to a snail if I open more than a couple of programs. Even just pressing the ubuntu button (that opens the unity panel) is very sluggish. But the speed between running this and windows is night and day.
Mint might be a good choice, or even maybe ElementaryOS, although that's still in very early beta stages (although what isn't in the open source world). I recently tried out Jupiter and it was very speedy on 512mb. Couldn't do wireless, so I had to run a 25' long ethernet cable just to really try it out, but I've been wanting a wired connection for a while now so it wasn't in vane. Ultimately though I switched just because it is barebones basics.
Hmmm, you booted straight from the CD correct? Then install to hard drive, put in your name, picked a password, location, etc. It might be possible that you installed it on a flash drive or something by mistake (I did this the first time I installed linux). The reason it needs the CD is because it wasn't installed on the harddrive correctly or because you wiped it with DBAN so it has no OS on it now, so it can't boot from the HD. It can only boot up from a CD or flash drive. Remove all external storage devices from your computer and then try installing straight to your HD (if you know its name that helps a lot). Otherwise, not sure what the problem is.
