forgotten password

I found this in How-To Recover password under Ubuntu you forgot you password for your ubuntu system you can recover using the following steps Turn your computer on. Press ESC at the grub prompt. Press e for edit. Highlight the line that begins kernel ………, press e Go to the very end of the line, add rw init=/bin/bash press enter, then press b to boot your system. Your system will boot up to a passwordless root shell. Type in passwd username Set your password. Type in reboot Good luck
