I've installed Grub2 through Debian, as I'm not aware of any other way than installing a full distro. However, when I experiment with different Puppy Linux versions, I need to modify the grub.d folder and then boot into Debian to run update-grub. This process is quite inconvenient.
I'm wondering if there's a way to move the grub.d folder to a separate partition (ideally my windows EFI partition) while still being able to update grub without booting into Debian every time.
Any help or suggestions would be greatly appreciated!
