Not sure why you would want to specifically do that since you can boot from a normal graphics install and just use the shortcut ctrl+shift+F# to change to the TTY.

However if you really want to just edit you GRUB config and copy paste the the menu entry you want to duplicate, and to one of them add a “space” and the number “3” to the end of the line. This way one entry would boot the graphics mode and the other would boot directly to TTY.

The solution is found here linux.org/…/grub-menu-entry-to-boot-to-tty.44508/ and perhaps a thread like this would better fit here !linux4noobs@programming.dev
