I have made a GUI (python3) to manage (create, remove, sort) the EFI boot loaders on multi HDD machine.
This GUI is based on efibootmgr commands.
If someone is interested, i can give this program. It runs under Debian like OS (debian, ubuntu, kubuntu, mint). I use the pre loader Refind, and there are on my computer many SSD/HDD with Debian, Mint, Windows 10 and Windows 11.
You can use it, correct it, its free. I’m not a programmer, so you can surely improve it.
