Your original description says that you created one partition, then the installer created the other. You probably didn't create the first one correctly so it wasn't actually a bios_grub partition, so the installer created one.
If you don't want to boot in bios mode, then you don't need a bios_grub partition at all; you need an EFI system partition. If the installer told you that you need a bios_grub partition, then you booted the installer in bios mode. If that isn't what you want, then you need to boot the installer in EFI mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1780015 Title: Installer gparted creates 2 BIOS boot partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1780015/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
