BIOS update failure

[SuperSEGAGamer]

When attempting to install the recommended BIOS update from F.54 to F.55 using the HP Support Assistant application, the update stalls after clicking "next" on the "HP BIOS Update and Recovery" popup, providing the error "086F3F55 There is not enough free disk space to complete the System BIOS and Device Firmware update operation. Delete some files to free disk space then retry again." despite having nearly 130GB of free space on my primary drive.

Greetings @SuperSEGAGamer 

Welcome to the HP Forum.

The HP BIOS update does its magic using the W10 EFI System partition.

A BIOS update is not always necessary if your PC is doing well. 

Your W10 installation probably has a 100 MB EFI system partition and it is probably close to full. This is why you see the "not enough free disk space" error.

You would have to expand the W10 100 MB EFI system partition using partitioning software or try doing the BIOS update using a HP BIOS recovery USB drive.

Scroll down to "Recover the BIOS using a USB recovery drive" at this HP Site for details.

Using partitioning software is somewhat more involved. It requires creating unallocated space immediately after the EFI system partition by shrinking the system root drive where Windows is installed. Then you would merge this free space into the EFI system partition to increase the size of this partition.

I have done this using Macrorit free available at this Site.

There is a chance of breaking Windows if the partitioning software is used incorrectly. So you would have to accept the risk involved.

I do routine Windows system image backups which allows a quick Windows OS recovery if things go south. I also routinely do data backups.
