How to create system reserved partition manually?

I recently installed windows (10 Pro) on a new ssd.
The boot manger etc were left on another ssd, but buy copying the boot and efi folders form the installation media usb drive I was able to make the new installation bootable. (GPT not MBR so couldn't use the other commands while in the RE of the installation media drive)

The only problem is it on has the 16 MB partition as well as the main one taking up the rest of the drive.

So I cannot run windows update since there is no 500 MB system reserved partition.

Using minitool partition wizrd, I took off 10 GB, floated it to the left, and made 3 new partitions.
It has an option to change the partition type ID, but the only one I recognize there is the one on that 16 MB partition, and I dont see any for system reserved.

It has the option to manually enter one in however.

In theory if I change that to be the correct one, windows should see it as the system reserved partition and use it properly.

Hi all, thanks for taking some time out to give some solutions.

Also, sorry for replying late.

I ended up fixing it by assigning drive letters to them, as well as the ones on another system, copying to files over accordingly, and then reading the ID codes on the other system and entering them in on another.

Was able to update windows.

Only issue I ran into was the new duplicate efi\boot folders took priority and I'm assuming its the BCD-Template file in System32\config that is setup to point to the one I copied to my C:\ partition. So I just swapped to the other "boot manager [my ssd]" of the same name in the bios and it worked.

Just migrated/cloned to another ssd to see if that one will also be bootable.

It worked and while sitll in the first os I was able to delete the other files so the boot mgr/efi folder were in the correct partition, and that was bootable on the new drive.
