How to get more EFS/UEFI memory

[maker]

Dell 5515 BIOS upgrade fails due to not room in EFS partition. I don’t understand this stuff but read that is allocated to something called UEFI used to boot the laptop. I can see 97MB of the 100MB partition is used. Windows Disk manager will only shrink C: form the right whereas I need an unallocated partition to the left. I’ve tried windows tools and free versions of partition tools but none will allow me to shrink Windows C from the left, or create an unallocated partition and move that next to the UEFI partition so I can expand that.

UEFI is a partition used for the bootloader and can not be modified as it’s controlled by Windows

Is there anything else I can do? Seems strange it is configured as 100MB, cannot be changed and has run out of space after a year so no more BIOS updates possible

You would need to do a fresh install of Windows 11 and modify the partition upon installation

moving a partition ‘from the left’ requires ALL data on the partition to be moved so that the proceeding partition can then be expanded.
not something Windows Disk Manager can do, as you have discovered.
I bought EaseUS Partition Master many years ago and use that for the few times I need to play around with partitions - but even it will have to move all your GB’s of system and personal files to make room.

you have no easy path ahead I’m afraid.
