Create a folder in your C: drive, call it temp and retry.

Ah, my bad. I did that and got:

Code: 
C:\Windows\system32>bcdedit /export C:\temp\bcdbackup
The store export operation has failed.
The parameter is incorrect.

C:\Windows\system32>

it added a bcdbackup.file to c:\temp


C:\Windows\system32>
 
Windows 10

  • Setup in BIOS/MBR mode creates a minimum 100MB System Reserved partition, a Windows partition and a 450MB WinRE partition (minimum 300MB).

  • AF 512e drives supported in both BIOS/MBR and UEFI/GPT modes.
  • Setup in UEFI/GPT mode (for 64-bit only) creates a minimum 100MB EFI System Partition (ESP), a 16MB Microsoft Reserved Partition (MSR), a Windows partition and a 450MB WinRE partition (minimum 300MB).

  • The ESP must be formatted as FAT32. On AF 4Kn drives the minimum ESP size is 260MB due to FAT32 partition size being calculated as sector size (4KB) x 65527 = 256 MB


I'm guessing mine must be BIOS/MBR mode?
 
You will need a bootable Windows disc or recovery flash drive to boot from to do this.
How to create a recovery flash drive: https://support.microsoft.com/en-us/help/4026852/windows-create-a-recovery-drive

After you create the recovery drive, boot from it by using the advanced startup options and choosing boot from device (or using the UEFI interface, whichever is simpler :) ).
Here's the instructions that other users have had success with:



Alright, apparently the issue is with the BCD (Boot Configuration Data). A few users reported that rebuilding it solved that issue.

https://answers.microsoft.com/en-us/...4-9ae12cfd89a2 - "Most Helpful Reply" from Cifad

If you cannot read the commands properly, here goes (to be entered in the command prompt from the Recovery Environment):

diskpart - Opens the Disk Partitionning tool
select disk 0 - Will select your first hard drive (the one with the Windows partition on it)
list volume - Note the number of the partition that have no drive letter assigned to it, is of 260MB of size and have "FAT32" listed under the "FS" column
select volume X - X will be the number of your partition with a size of 260MB, the EFI System Partition one that you identified in the last command
assign letter=Z: - It'll assign the Z: letter to the EFI System Partition
exit - To exit the diskpart utility

Now you'll be back in the command prompt, enter the following commands:

cd /d Z:\EFI\Microsoft\Boot - Goes to the "Boot" directory in the Z: partition
attrib Z:\EFI\Microsoft\Boot\BCD -h -r -s - Removes the hidden, read-only and system attributes from the BCD folder
ren Z:\EFI\Microsoft\Boot\BCD BCD.old - Renamed the BCD folder to BCD.old
bootrec /rebuildbcd - This command will rebuild the BCD.

When it asks you Add the installation to boot list?, press on y followed by Enter and if it succeed, you'll have a The operation completed successfully message. Once you're done, close the command prompt, restart your computer and try to upgrade again.



Make sure you have a complete backup of anything important on your computer BEFORE attempting any of these steps.

Make sure you don't progress to the steps, but rather just determine the type of your System Reserved Partition.

Too late I already did the needed steps on that support page and it cleared up space on the system reserve partition.

I then ran windows update again, it told me to go download the fall creators update tool. I did that and everything updated just fine.

Thank you for all your help! (sorry for the late reply)
