Sto se tice lozinke, moguce je prebaciti linux na single-user mode tako da ne trazi lozinku, evo sta sam pokupio sa nekog sajta (nadam se da se snalazis sa englskim):
"If you wish, you can easily reset your root password locally by logging into single-user mode.
When you first start your system (either by lilo or a floppy) you will see a prompt that says boot: or lilo:
After one of these prompts you type...
linux -s
or
linux single
You will then see a bash# prompt. Then at the prompt you enter...
passwd
It will prompt you for a new root password. Type reboot at the prompt to restart the machine and login again. (I had to do this once on slackware for reasons that escape me at the moment)
Redhat explains how to do it with the Grub bootloader here...
