Grub Customizer VS efibootmgr

Grub-customizer hasn't been updated in 3 years, I wouldn't let it near my config with a ten foot pole. Source: over 2 years ago

If you can install Ubuntu packages, https://launchpad.net/grub-customizer might do it. Its a GUI to edit grub entries, seems easier than switching bootloaders to me. Source: over 2 years ago

Grub-customizer is supposed to be maintained on Launchpad Https://launchpad.net/grub-customizer But the last version of the package was released 2018-10-13 and the main developer only responded to 1 bug report this year - but it is confirmed to work on Ubuntu 19.10! Source: over 2 years ago

When I use the command line tool efibootmgr to modify the UEFI's boot entries, it fails with Could not prepare Boot variable: No space left on device. But I am not sure which device efibootmgr thinks is full; sda1 has plenty of space and is mounted writeable; it seems to be something directly by the BIOS? -- The same message appears when I want to reorder Bootnums, but the reordering still is carried out.

Efibootmgr wiki Use this reference to change boot order if you so choose. Reboot into bios and you should see your windows install as an option to boot. Source: over 1 year ago

So I updated the install script to use efibootmgr to change the boot order. It's updated from the looks of things, but the CDROM still boots. Even when I use it to delete boot entries, it continues to kick the Live CD. When I change the EFI boot order manually in the vSphere client or disable entries, it will boot the installed Arch Linux.

Assuming you are using EFI you can use https://github.com/rhboot/efibootmgr to change your boot order. This will bypass GRUB. I would create a bash alias to change the next boot device and then restart the computer so you can have everything happen with one command. Source: over 2 years ago
