I had a PC running Ubuntu 12.10. Haven't used it much after installing OS. Now I can't remember the password.
Tried to go to single user mode to reset password, unfortunately, when pressing SHIFT during boot, it doesn't stop at boot menu. I can see the boot menu in a split of second and it disappeared.
This PC doesn't have a USB drive, so it's kind of difficult to run rescue CD.
Any idea how to stop at boot menu so I can go to single user mode?
Thanks in advance.
