I want to increase the timeout in the grub boot-menu (on an UEFI machine with several OSs).
I’m used to grub-customizer on Ubuntu, but I’ve read that is deprecated in Manjaro, because it somehow conflicts with the system’s boot-configuration.
How do I do that in a way that
it doesn’t conflict with the Manjaro boot configuration?
Thanks. That did help me to find a way to configure grub.
But unfortunately only editing this file didn’t change the boot menu. I think I must envoke some command like grub-install or similar. But I’m afraid to do that because this is not a Legacy BIOS PC, it’s UEFI!
