I installed ubuntu and set a password, after some use I decided that I don't want to type password every log in to my comp so I desabled the password completely
now when I try to do something that require root premissions and type the password I setup ubuntu with it doesn't work..
I tried the common way to reset pass, http://www.psychocats.net/ubuntu/resetpassword
press shift while rebooting the comp and in GRUB choose linux in rescue/recovery mode, but I doesn't have the option
any option other then re-install ubuntu?
thx for help
