Removing old EFI System partition and converting 3 partitions into 1.

I recently upgraded my PC by installing an m.2 SSD which upon I reinstalled Windows 10. The PC works great, load times are almost nonexistent and I'm very happy.
My problem is now with the old regular SSD. It was set into 3 partitions, a ~370MB reserved drive (partition 1), a 100MB EFI System Partition (partition 2) and the rest of the 223GB as data (partition 3). I formatted the drive and that emptied out partition 3. Then, after reading a few of these Ask Microsoft questions, I used diskpart to delete partition 1.
The drive now looks as follows.

When I use diskpart to try to delete partition 2 using

delete partition override

I get the error message "The operation is not supported by the object." Diskpart lists the partition type as "system".


I don't want to just ignore the 100MB allocation as it's no longer a boot drive and not necessary at all. It's more principle at this point. But even if I did, I can't seem to merge the two remaining drive partitions 1 & 3 either.
One suggestion from another page was create a volume on one of the unallocated volumes and use the extend command to push it into the other unallocated space. Right clicking on the disk 1 and selected properties tells me that the drive has a capacity of 228,809MB with 228,709MB unallocated. Makes sense. Creating a simple volume from the right hand unallocated space gives me a max size of 228,335MB capacity. After it finishes formatting it, I try to use the Extend Volume command to add 370MB, I get this message: -


The operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed operating systems from any volume on the disk(s) (except the current boot volume). Are you sure you want to continue?"

I don't fully understand the difference between a basic volume and a dynamic one, but as I don't have any booting operating systems on this drive at all, I select "Yes".

After converting the drive to dynamic and turning it's header bar from blue to an olive colour, I get this error message: -

Doing the same with the left hand unallocated space first has the same problem. Extending tries to switch the drive to a dynamic one before telling me there isn't enough space to extend. Even if I try just extend by 500MB as a test. It still won't.

There is nothing on this drive I want to keep at this point. I'd just like to use it to install software and games. Is there anyway to completely reset the partitions and reclaim 100% of the space back? Is there a boot command that can do this so there's no chance my current windows on my now C: drive isn't interfering with it thinking it has a workable windows on it?


Many thanks in advance for your replies,
