Using GRUB, how do I boot in single-user mode?
Think I did something like this in the past; afraid can't remember the details; you'll probably have to look it up in 'info grub' - perhaps the menu.lst or menu.conf or whatever, configuration file, section.
Am not a pundit on this at all, but the thing looks a bit odd:
Is the problem that you haven't got the root, superuser, password? And the machine says you may get round this by using single user mode?
I cannot gainsay the machine, but surely it's a bit odd: It implies superuser priveliges are had by anyone who logs on single user. Bugger all point in the password then??
On the surface you can only reinstall.
