Healthy (Recovery Partition) and (EFI System Partition) on wrong drive.

I recently installed Windows 10 on my newly built PC. My 500GB SSD used for gaming seemed to have the Healthy (Recovery Partition) and Healthy (EFI System Partition) on it. My 250GB SSD for my OS seems to have 549MB of unallocated space, which I assumed to be the original place for the two partitions.

My question is, what should I do? Would having the two partitions on a separate drive affect anything? Can I move them to the OS SSD? Should I delete both partitions and use EaseUS to fill up the unallocated spaces in both drives?

Thank you

Yes, you can have a problem if you remove that disk and windows will not BOOT. You can do this: https://www.tenforums.com/tutorials/81502-convert-windows-10-legacy-bios-uefi-without-data-loss.html to make a UEFi partition and BOOT on that smaller drive.

I'm a little confused. What would that do and how would it affect the current problem with the two partitions on the wrong drive?

It would make UEFI GPT partition on the right drive so you can boot of it only.

You might want to try the following process. We've used it successfully to create an EFI System Partition on a GPT-partitioned drive that for one reason or another did not contain the EFI partition and thus was unbootable. We haven't used this procedure involving a situation precisely like the one you're experiencing but (hopefully!) it should work to create the EFI partition on your 250? GB boot drive which will become bootable after deleting the EFI partition from your 500 GB Disk 0.

But understand there are NO GUARANTEES HERE SO IF YOU DECIDE TO UNDERTAKE THIS PROCESS YOU DO SO AT YOUR OWN RISK. IF YOU DECIDE TO DO SO, ENSURE THAT BEFORE UNDERTAKING THIS PROCESS YOU FIRST CLONE THE CONTENTS OF YOUR C: DRIVE TO ANOTHER DRIVE SO THAT IN THE EVENT THE PROCESS FAILS AND YOU WIND UP WITH AN UNBOOTABLE SYSTEM YOU WILL HAVE THE MEANS, I.E.,THE RECIPIENT OF THE CLONE, TO RESTORE YOUR SYSTEM TO ITS PRIOR FUNCTIONAL STATE.

I assume you have at least a "passing acquaintance" with the DiskPart utility. If you don't, do a Google search on "using diskpart".

1. Access DiskPart.

2. list disk

3. select disk # (this is the disk where you want to add the EFI System partition - presumably Disk 2).

4. list partition

5. select partition 1 (the Windows OS - presumably Partition 1).

6. shrink desired=100
"DiskPart successfully shrunk the volume by: 100 MB"

7. create partition efi size=100
"DiskPart succeeded in creating the specified partition."

8. format quick fs=fat32
"DiskPart successfully formatted the volume."

9. assign letter=S
"DiskPart successfully assigned the drive letter or mount point."

10. Exit DiskPart

11. At command prompt...
bcdboot C:\windows /s S:
"Boot files successfully created."

12. Exit

13. Disconnect the 500 GB drive that presently contains the EFI System Partition from the system. DON'T delete any partitions or data at this time.

14. Boot ONLY with the 250 GB boot drive (you can include the 1 TB secondary drive) connected to determine if system boots to the OS and functions without any problems. If the system is COMPLETELY functional, connect the 500 GB HDD and delete the EFI System Partition from the drive. You'll probably need to use Diskpart to do so with the command "delete partition override" after selecting the partition.

15. Exit. You can also delete the Recovery partition.
