Yes, you don't have a MBR with GPT, you should be booting with UEFI,
however, if you need to BIOS boot a GPT partitioned disk, it's telling you
what you need, just could use some more details.

You literally need like a 2MB (yes megabyte, not GB) BIOS_BOOT partition. I
don't know how to do that in kickstart as it doesn't need a mount point,
just the correct partition identifier but hope this helps anyway.

I actually do this on one of my older computers that doesn't have EFI:

Model: ATA MKNSSDRE256GB (scsi)
Disk /dev/sdc: 256GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start   End     Size    File system  Name       Flags
 1      1049kB  3146kB  2097kB               BIOS_GRUB  bios_grub
 2      3146kB  1052MB  1049MB  ext4                    boot, esp
 3      1052MB  256GB   255GB                           lvm

Parted calls it "bios_grub", not sure if that's universal or not.

Thanks,
Richard
