I just tried it and it worked fine. I picked the default guided partitioning, then changed the root partition (partition 2) from ext4 to JFS. I did NOT delete and create any partitions from the default guided setup. I think, based on your error, that you deleted partition 1 (8MB the PReP boot partition) which is required for installing the boot loader in IBM power systems. Or maybe you change the use type to JFS from PReP boot. Partition 1 (PReP boot) does NOT contain a filesystem and is not mounted. Grub is written to it raw and the firmware loads the contents of the partition into ram and executes it raw. -- Len Sorensen
