How and is it possible to delete an EFI encrypted partition and a recovery partition from a "blank" drive?

Question

Windows

Hello. There are 2 disks, both had Win, but it was decided to leave Win only on one: the first one and delete it on the second -> Waking up, I got into diskmgmt and simply deleted the main partition on the 2nd disk, but there were recovery partitions and encrypted system Efi. There is no possibility of deleting the first one from diskmgmt, when trying to delete a partition, Efi writes that this partition was not created by Win, and can be used by another system.
If you go into powershell and try to delete the Efi partition there, it says that it is impossible to delete the active system disk.
So the question is - how to completely clear the second hard, and at the same time not break the first one?) And in general, am I acting correctly?)

Answer 1

diskpart
Close the command line and go to the disk manager, there we initialize a completely empty disk.
Just be careful not to mix up the discs.

Answer 2

I usually restart the computer from any LiveDVD / LiveUSB for such cases - as a rule, all (even the ancient hiren`s boot cd) have many tools for working with partitions, deleting them, creating and resizing them without losing information. To do such things from the most experimental OS is somehow dumb.

Answer 3

It's just a bug in Windows translation. It's not "encrypted". Put the English package and see.
