HP Recommended
Product: HpFirmwareUpdRec64
Operating System: Microsoft Windows 10 (64-bit)

If you happen to get this error code in your hpfirmwareupdrec log: when running from WinPE

 

Mount EFI Partition returned WMI Error. 0x8004102F
No BIOS recovery partition was found
HPFirmwareUpdRec Return Code = 260

 

I found an issue were our System (EFI) partition was assigned a Letter. Once I removed the letter and left it without one the upgrade process work as expected.
