Hi. I'm a totally newbie to linux, but so far I love ubuntu. Many things are easy, but I messed up my sudoers file on my usb live installation and can't figure out how to get it back. I put in a couple lines (to try to get a usb install working..) using visudo and didn't check that they were ok before submitting it and killing things. Reboot doesn't help, something is persistant but I can't find a /etc/sudoers file to edit anywhere on the usb stick when I access it when just booting up the live CD..

The standard "go into recover mode" doesn't seem to apply since it's a persistent usb-install?

Help is appreciated. Sorry for the newbie question.
