When your grub menu appears select advanced options. Hit e to edit the menu for the first kernel. Find the line with the vt handoff terms entered, (Comes just before the initrd line). Backspace out the line up to and including ro ( the space before the UID hex. Type in: rw init=/bin/bash and then hit F10. Try running your command in the bash terminal that appears. Don't know where you found it but I'm not sure the syntax will work. You can try it. Enter your sudo password when prompted and see if the mask command works. If your terminal prompt returns without any error message bash accepted the command. Don't worry about editing the grub menu. Changes are not saved involving boot instructions when you use the e command from grub menu. Use the up down arrows to navigate grub menu edit.
BIOS password has nothing to do with this unless of course your BIOS are already locked with one.

If you have no grub menu keep hitting shift while the system boots up until the message grub loading appears.
