When you create a mount point in custom partitioning, the 'mount point' text box has a drop-down list of commonly-used mount points. This includes an entry for the BIOS boot partition needed on BIOS-on-GPT installs, but not the /boot/efi partition needed on UEFI installs, which is probably a more common case than BIOS-on-GPT. It should probably be added to the list.
