I have big problem. My Linux Ubuntu 9.04 (64bit) don't allow me to log in anylonger. I even tryed to use "root", but still I cant log in. I think, I changed something, what I should not have to done. What I changed was in, where was log in users... /root... and something like that. Can someone help me? Or Do someone know how can I re-Install Linux Ubuntu 9.04 (64bit)? I have Windows Vista in same PC...
Boot with the recovery mode option in the boot menu. It should just drop you in a command line as root. Then try resetting the password of your user with "passwd [user]". If that doesn't work just reinstall, the same way you put it on there in the first place, not worth trying to repair all the damage you could potentially have done, just be more careful when working as root.
Hi and welcome to our humble abode. However, thread title renamed from "I have big problem with linux... Requesting help!...", a title in a forum of the same name is as bad as "Please Help". In future please see here about thread titles ~ http://forums.afterdawn.com/thread_view.cfm/440385
