Title: Add an option to seamlessly switch between GRUB and systemd-boot

Comment:

Is your feature request related to a problem? Please describe.

Switching between GRUB and systemd-boot can be tricky, with the risk of leaving the system unbootable if something goes wrong. A clean and safe way to convert between these bootloaders would be incredibly useful for users looking to experiment or optimize their setup.

Describe the solution you'd like

It would be great if Linutil could provide an option to easily switch from GRUB to systemd-boot (and vice versa) while creating a backup of the current bootloader configuration. This way, users can safely test different bootloaders without worrying about breaking their system.

Describe alternatives you've considered

While manual bootloader switching is possible, it involves several complex steps. Automating this process in Linutil would significantly reduce the chances of errors and improve usability.

Additional context

Offering a safe bootloader switching option would add great flexibility for users. Thank you for all the effort you've put into making Linux easier to use!

Thank you so much for all the hard work you've put into this project. Linutil is an amazing tool, and it’s truly making Linux more accessible and user-friendly. I’ve also suggested a few other features in separate issues that might interest you, and I’d be excited to see any of these improvements considered.

Again, I really appreciate the dedication and effort from the development team. Keep up the great work, and thanks for making the Linux experience better for everyone! 🙌
