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? -- [tim@localhost ~]$ uname -rsvp Linux 5.0.16-100.fc28.x86_64 #1 SMP Tue May 14 18:22:28 UTC 2019 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.
