Changing Boot Order in systemd-boot for Dual-Boot Setup with Windows using UEFI
In a dual-boot setup, you might want to change the boot order to prioritize one operating system over the other. This article will guide you on how to change the boot order in a systemd-boot setup with Windows using UEFI.
Understanding systemd-boot and UEFI
Before we dive into the process, let's briefly understand what systemd-boot and UEFI are.
systemd-boot is a boot manager that is used in place of GRUB in modern Linux distributions that use the systemd init system. It's designed to be simple, fast, and reliable.
UEFI (Unified Extensible Firmware Interface) is a modern replacement for the traditional BIOS. It provides a more flexible and secure way to boot operating systems.
Accessing systemd-boot
To access systemd-boot, you'll need to enter the UEFI firmware settings. The method to do this varies depending on your system's manufacturer. Typically, you can press a key like F2, F12, or Del during startup.
Editing the systemd-boot configuration
Once you're in the UEFI firmware settings, locate the systemd-boot entry and select it. You should see an option to edit the boot options. Select this option, and you'll be presented with a text editor to edit the boot loader configuration.
Changing the boot order
The boot loader configuration file for systemd-boot is usually named bootx64.efi. It's a simple text file with entries for each operating system. Each entry has a unique identifier (UUID), and the order is determined by the order of these UUIDs in the file.
Here's an example of what the boot loader configuration file might look like:
title Windows Boot Manager
efi /EFI/Microsoft/Boot/bootmgfw.efi
options scsi-id=0x2400 rw,chain
title Ubuntu
efi /EFI/ubuntu/grubx64.efi
options root=UUID=<your UUID> ro quiet splash
To change the boot order, you need to rearrange the UUIDs. For example, if you want to prioritize Ubuntu over Windows, move the Ubuntu entry to the top of the file:
title Ubuntu
efi /EFI/ubuntu/grubx64.efi
options root=UUID=<your UUID> ro quiet splash
title Windows Boot Manager
efi /EFI/Microsoft/Boot/bootmgfw.efi
options scsi-id=0x2400 rw,chain
Saving and Exiting
After you've made your changes, save and exit the text editor. You'll be prompted to confirm the changes. Make sure to save the changes before exiting, as any unsaved changes will be lost.
Rebooting and Testing
Finally, reboot your system to test the new boot order. You should now see the operating system that was moved to the top of the boot loader configuration file boot first.
