Bios Update: Not enough free disk space

[DK111]

The operating system disk as below:

GPT Recovery Partition 499mb used 10.23mb 

EFI System Partition 100mb used 49.02mb 

GPT Reserved Partition 16mb used 16mb <free 0B>

Data Partition 237.87GB used 43.88GB

I created a USB bios recovery drive. The files needed for recovering / updating the bios require 108mb of space on the USB disk. I think the EFI partition on the system disk does not have sufficient free disk space. Just a guess!!

Solved:

<update the bios when windows does not start>

using a bios recovery USB disc. 

The bios management, by default, was loking for bios files on partition 2 (EFI partition). 

I believe this is where the problem was.. "not enough disc space"

Make sure to turn off Bitlocker. Its usually the EFI system partition that is used for BIOS update and yours appears to have plenty of room. You might try an alternate method to update the BIOS:

Yes, updating bios using a USB drive worked. Thanks for the support.
