Let me explain in order. You created a F.27 BIOS recovery USB. Thats correct? When you insert a USB flash drive into a laptop port, the BIOS can access the flash drive with firmware management software on it. BUT hewlett packard uses the same software for BIOS updates too. And hold up, the BIOS can be updated without a flash drive. To do this, the update program moves files in the ESP partition of local drive. This means that the HP folder on that partition will prevent the software on USB flash drive, because when updating the BIOS, the image file is sent to a folder named "New", and for recovery to "Current". Make sure the ESP partition does not have an HP folder before using the USB drive. BIOS reads internal drives first.

 

So, this is why people disconnect the Hard Drive when updating through USB!!
