I am sorry if I have posted this in the wrong section. Please forgive me.
I have a problem that I just can't seem to figure out.
I was given a copy of ubuntu that is running on a bootable USB stick. Unfortunately, the person who gave me this USB installed copy gave me the wrong password for root. Everything they have told me to try has failed, and I cannot get root access on the installation.
If it were a basic installation, I would just reinstall and forget about it, but this particular installation has some tools on in that I cannot get access to otherwise.
The grub menu is set for a 0 timeout, so I can't see the menu to select recovery mode in order to change the password. Because it is a bootable USB stick, I also cannot figure out how to access the file system in order to manually copy, edit, and replace the shadow file with the password removed.
Does anyone have a solution to my problem? How can I get to recovery mode on a USB installation with a grub timeout of 0?
Any help would be greatly appreciated.
