If you can do this then be sure that the EFI partition is formatted vfat (fat16) and is at least 100MB in size. If you're running any Linux distribution (including Ubuntu) then it's convenient to use an EFI partition for the boot loader instead of MBR. You need a EFI partition to do the BIOS upgrade. Maybe that EFI partition is required for BIOS upgrades through local media? As I understand now, the laptop came with an EFI partition with some HP software related to BIOS and firmware. When I installed Ubuntu on the laptop I erased everything on the SSD. No, I haven't figured out the why the BIOS reports invalid image when attempting to update from local media.īut I have a guess, maybe it could be related to this:
