GRUB menu always appears on boot despite not dual-booting

Question

I run a fully Windows computer with Kubuntu installed on an external drive. Even when the drive isn’t plugged in, the Grub command terminal appears on boot and I have to type exit to stop it.

It’s just an inconvenience, but is there any way to make the menu simply not appear whenever the drive isn’t plugged in? I’m not technically dual-booting so I don’t know why the menu appears in the first place.

Welcome, it's because when you installed Ubuntu, the bootloader GRUB was installed in your internal drive, not in the external (In the process of installation you can choose where to intall it). So you have to reinstall the windoes bootloader. — schrodingerscatcuriosity, Feb 08 '21 at 17:44
Take a look at this post for example, but you can find many more. If your machine is EFI configured, it could be more complicated. — schrodingerscatcuriosity, Feb 08 '21 at 17:48

Check the Grub Customizer

sudo apt-get install grub-customizer

Run, then:

General settings -> Show menu (uncheck)
