GRUB itself is passworded? Or can you get to a login prompt?

at boot :

linux init=sh (or bash, zsh etc)

then remount / in read write mode with :

mount -o remount,rw /

Now you should change your password with :

passwd

Good luck !

What do you see? Does it stay at GRUB? Does it go past GRUB? What does
it look like? Please give details.

Then, when you get the shell just type 'passwd' to change the password

no it doesnt stay at GRUB, it goes ahead to booting process and then login screen, is there a way to stop it? the other details at grub include press 'c' for command prompt, when i press 'c' the prompt looks like GRUB>

press e instead of c.

Edit the line which has

kernel=....

at the end of the line add single

and resume the boot process. This will land you in the single user mode where you can change your root password.
