Insydeflash Windows BIOS Flash Utility: Tips and Tricks for Successful BIOS Flashing

Thank you! What worked for me was download and install HP PC Hardware Diagnostics UEFI 7.7.0.0, it added the UEFI partition to my recently wiped hard disk, restarted the PC, pressed ESC, then F2 to enter diagnostic utility, and from there I could upgrade the BIOS manually for my HP 15-ac135la. Without your info I cound've never upgrade the BIOS. Thanks!!!

4) I'm wondering, is your flash utility up to date? How old is your version? Might be wrong, but maybe there's no support for newer BIOSes in your utility (sounds stupid, I know, but I just try to make some ideas).

Note: The USB flash drive format must be FAT32 so that you are able to update BIOS in the BIOS utility. Here you can learn more about How to convert the USB flash drive format to FAT32. 2ff7e9595c
