Windows 10: How to move EFI System Partition?

I'm in a bit of a weird situation.

A couple of months ago, I did a fresh install of Win10 onto a new 1TB M.2 SSD I had recently bought, wanting to use the old 500GB SATA SSD for something else.

The computer runs flawlessly and boots up quickly (besides asking me which Windows install I want to start).

I recently went in to format the original SSD and saw that it somehow still has the EFI partition, so to test my theory I tried unplugging the SATA and starting up the computer. The computer is unable to get past BIOS after that. Image of disk management for reference.

How on earth did I do this, and how on earth do I get the EFI partition onto my M.2 drive so I can reclaim the SATA as an external?

Move EFI partition

its to enable win 10 to update to its anniversary edition.. it cant do this due to lack of C drive space i have had a quick try with the trial version of easus.. it didnt seem to be able to do what i want..

i am assuming i cant just delete the efi partition but maybe i could.. as yet i havnt even figured out how to get into the bios of the thing.. maybe that should be my next step.. *Smile

diskpart could probably do it but figuring out how (it aint that user friendly) might be difficult without step by step instructions..

EFI System Partition

So, an EFI system partition is perfectly normal on a Windows 10 disk (I assumed you've done an internet search and discovered that this partition is for booting your system).

Are you trying to backup the contents of this partition?.... if so, what software are you using?
