Upstream offers the current names "GRUB" = "GRUB 2" for versions above 1.0 and calls the old versions 0.XY "GRUB Legacy". https://www.gnu.org/software/grub/ The name "GRUB1" seems to be an invention of users discussing the differences between both GRUBs. "GRUB-PC" seems to stem from Debian binary package "grub-pc" for BIOS/x86 in contrast to e.g. "grub-efi-arm64". Those are all made from GRUB2 sources since quite a while. I write "GRUB2" and "GRUB-Legacy" to avoid ambiguity. The "-" is added to make clear that "Legacy" is part of the name. Have a nice day :) Thomas
