so I booted up an old Linux Mint machine today and I can't seem to remember the password. So I wanted to reset the password using the instructions on Mint's website but when I hold shift the GNU GRUB boot menu does not seem to come up. It just asks me for my password then shows me the login screen.
To clarify, I know the system password but not the login password.
I initially assumed it was because I was using a USB keyboard at first but that does not appear to be the problem as it is recognizing the keyboard immediately and I can enter Bios.
Any help would be appreciated.
