It will no longer allow you to install grub on a partition,
it only uses the disk block device.
Aha, now we get to the core problem.
It sounds like that would be simply solved if the installation routine
let you:
a. Do not install a bootloader, let me use something else (something
you've already got, that you're prepared to configure, yourself).
b. Do not re-partition or re-format drives, let me select existing
partitions to install to.
As far as I can recall, it used to let you do both. It definitely used
to let you do the second one. I haven't tried multiboot installs for a
while. I have *one* PC with Fedora 28 & 30 on two different drives.
Multibooting has always been several kinds of pain. UEFI has changed
the game in another way, you're supposed to let it choose what to boot.
GRUB has become worse, too. It's almost totally incomprehensible to
customise. The old single grub.cfg file was easy to understand and
modify. I wonder if modern GRUB can read the old config format?
