I solved this by turning off 2.2 tb infinity setting in the bios. The board does NOT have a UEFI bios. The installer reads off some bios information somehow and the installer thinks if the infinity mode is on, that this is a uefi bios. Noway nohow can this board run a uefi system partition.
Board is an MSI 7596 760GME51 https://us.msi.com/Motherboard/760GME51/Overview I originally thought it was uefi but it was a fake out, I have a whole thread here and it was finally explained to me. https://forums.linuxmint.com/viewtopic.php?f=46&t=248272&sid=776ccd7425ee9d048bc6ff30404a00a9 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748879 Title: UEFI issue, installer thinks board is uefi, but it is not To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1748879/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
