I have installed nimdow window manager. I have auto-login enabled. Nimdow is the default option. The only options I have at boot are (from the bootloader): default, timeout, edit, resolution, print and help (help is not working). How am I supposed to go back to GNOME or disable auto-login? I tried accessing the recovery shell, but I can't access it by spamming escape. Someone PLEASE help. Google Bard is useless.
You are probably gonna want to chroot into your laptop using a livecd for linux. This will allow you to basically access your terminal without being able to login or boot, and then you can uninstall Nimdow, or turn off auto-login.
Some guides to chrooting.
