Thinking more about it, there may be several ways to install
grub files, namely either on the MBR or within the target
partition. You probably chose the former (or this is the
Mint imposed way) so you hit the space limit before the first
partition. I installed Fedora which apparently did the other
way (I do not remember having been asked about it).
