Grub Reboot Picker is a tray application that helps you reboot into other operating systems or kernels, UEFI, BIOS, or just reboot.
What it does
The application autostarts with the OS and sits in the system tray as an application indicator. Click the icon and a list of options appear, such as UEFI, older kernels, other OSes, and of course Windows. Even if you don’t dual boot, it’s still convenient to be able to boot into UEFI/BIOS.
When you click one of the options, the system will reboot and the next time the Grub menu appears, your selection will be preselected. This allows you to set a small timeout on the Grub menu.
I’ve only tested this with Ubuntu 18.04 and 20.04 but it should work on any system which runs grub and Gnome.
How to install and run it
It’s available in my ppa, run these commands:
sudo add-apt-repository ppa:mendhak/ppa sudo apt update sudo apt install grub-reboot-picker
You can then reboot and the reboot icon will appear in the system tray.
Or you can search for Grub Reboot Picker in the Gnome Activities search.
Or you can run
grub-reboot-picker from the command line, or search
How it works
The appliction basically parses
/etc/default/grub and lists out the entries in the system tray menu. When an item is picked, the application uses
grub-reboot and passes the user selected entry, and then runs the
Since the grub file also contains entries for UEFI/BIOS, it’s also convenient even if the system is not dual boot.
