Assuming that this (sdb) installation is bootable on your computer, the
problem appears to be that you've booted in BIOS mode on a system that's
UEFI-capable. If you boot in UEFI mode, you can reuse the EFI system
partition on sdb (if you choose to do that), and you don't need to shift
partitions about. You would need to mount the existing EFI system
partition at /boot/efi.
If you don't want to share the EFI system partition, then you will need
a new EFI system partition on sda, for your new Fedora installation.
If you want to continue to use the system in BIOS mode, then the
installer requires a 1MB biosboot partition at the beginning of a GPT
disk in order to reserve space for grub. You *might* be able to simply
create one in the unused space from sector 34 to sector 2047.
