I can't start my computer. Hardware diagnostics checked out OK so I'm trying to update my BIOS. I followed the guidance at https://support.hp.com/us-en/document/c00042629 but got stuck at step 7. According to step 3 number 2, the BIOS image name should match the system board ID. Unfortunately, there is no exact match available on the USB recovery drive. My system board ID is 81EB but the only ones on the recovery drive end in EC, ED, EF, F2, and F3. I'm pretty confident that the operating system on the laptop was Windows 10 (64-bit).
