Hi everybody!

I had SSD and HDD in the system on dualboot win 10, later i removed the hdd and the ssd win wouldnt boot. when placed the HDD back, the SSD Win still wouldnt boot. After booting from HDD in disk management the SSD windows partition showed as EFI system partition and i could not access data on it.

Then in disk part I changed the 238GB EFI System partition to basic data partition using these commands:
diskpart
list disk
select disk x (select SSD - probably disk 1)
list partition
select partition y (select 238GB EFI sys partition - probably partition 2)
set id=edb0a0a2-b9e5-4433-87c0-68b6b72699c7 override

No the partition type shows as unknows and it is not tied to any volume. Pls see screens. What should i do to get access to data stored in that 238 GB partition.

Here is what i get in diskpart:

as you can see, in the list of partitions its type is unknown and there is no volume on this partition. Why is that?

And here is how the Disk Management in Windows sees it:

cannot assign a letter....
 
Can we assume there's zero (0) data on your 256 GB SSD? drive? If that IS the case just simply use DiskPart to "clean" the drive and then partition/format the drive as you please. If you initialize the drive to GPT, please do NOT delete the EFI 100 MB - 128 MB that will be created. I have no idea why you did so previously.
