    Enter new UNIX password:
    Retype new UNIX password:
    passwd: Authentication token manipulation error
    passwd: password unchanged
    
    Your root partition is mounted read-only. Try:
    # mount -o remount,rw /
    
    to resolve this issue.
    [ end Kernel panic - not syncing: Attempted to kill init! exit code=0x0007f00
    
    Make sure that you removed splash boot option when editing grub's menu item.
