Tenyleg nagyon drukkoltam, hogy sikeruljon.

Nemtudom mennyire komoly a gond aztsem ,hogy milyen boot loader-t hasznalsz nekem ez mukodott =>
Booting into single user mode from GRUB

Follow these steps to reset the password when using GRUB:

    * Reboot the system, and when you are at the selection prompt (See Fig. 2 below), highlight the line for Linux and press ‘e’. You may only have 2 seconds to do this, so be quick.
    * This will take you to another screen where you should select the entry that begins with ‘kernel’ and press ‘e’ again.
    * Append ‘ single’ to the end of that line (without the quotes). Make sure that there is a space between what’s there and ‘single’. If your system requires you to enter your root password to log into single-user mode, then append init=/bin/bash after ‘single’. Hit ‘Enter’ to save the changes.
    * Press ‘b’ to boot into Single User Mode.
    * Once the system finishes booting, you will be logged in as root. Use passwd and choose a new password for root.
    * Type reboot to reboot the system, and you can login with the new password you just selected.

Itt tobb megoldas is van es persze az idezet is innen szarmazik.
