Cause

[SAS:PCIE4:Bus 00-225DD1F5 HITACHI H10906]

[SAS:PCIE4:Bus 00-225B1365 HITACHI H10906] -----> O/S installed on second disk.

The output above may differ depending on platform configuration and disk type.

Since the disk which contains the Operating System (O/S) installation is second in the BIOS/UEFI boot priority order, the message "Bad PBR sig" shows during platform initialization as there is not a valid boot record on the first disk in the boot priority order.

Solution

Move the OS disk [SAS:PCIE4:Bus 00-225B1365 HITACHI H10906] to Top of the Boot Priority list in BIOS.

This resolves showing of the "Bad PBR sig" message.
