Or maybe you changed 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. Can you try one more time, Pick the default guided partitioning, then change the root partition(partition 2) from ext4(or <xyz> filesystem) to JFS.Do not delete and create any partitions from the default guided setup. Paste the results.

Paste the results. No, I have not deleted partition and I have not changed the use type to JFS from PReP boot. Any ways I tried again and it still fails. ??????????????????????????
