A gnome-shell extension to add a "Custom Restart..." option to the shell system panel that allows you to choose what OS you want to boot into, after which it triggers the typical end session dialog for restart.

This extension needs permissions for gnome-shell to read your /boot partition, please verify your Linux distribution documentation.

There is now a button in the dropdown to make grub.conf readable (Requires authorization)

Known Limitations

The GRUB reboot option is known to not work on Fedora or any Arch based distro. Please use efibootmgr or systemdboot

gnome-extensions install --force customreboot@nova1545.shell-extension.zip

(Post-Install) Set Boot loader options

Open the extensions settings and choose from efibootmgr (default), grub, and systemd-boot. The extension will try all enabled boot loaders in the order show in the settings window, until one is found that works.

Systemd-boot

It's able to set the one-shot default using bootctl set-oneshot ID.

The presented options are parsed from bootctl list.

When you select the operating system to reboot into, you'll be required to input your password because of required permissions to run bootctl which set EFI variables.

GRUB

It's able to set the default menu entry using grub-reboot title

The presented options are parsed from the grub config.

When you select the operating system to reboot into, you'll be required to input your password because of required permissions to run grub-reboot.

efibootmgr (New)

It's able to set the default using efibootmgr -n 0001

The presented options are parsed from efibootmgr

When you select the operating system to reboot into, you'll be required to input your password because of required permissions to run efibootmgr which set EFI variables.

Caveats

I've only tested this on Ubuntu running GNOME 43 and GRUB. Please let me know if you run into issues on other distros, bootloaders, and GNOME shell versions.

Pull requests welcome!
