Delete EFI partition on external drive.

I've been having problems regarding SSD cloning. Macrium have been very helpful. It appears that I'm booting from the 2 installed internal hard drives (!?!).

It was working OK for ages but obviously something subsequently has happened.

It was recommended I clone to an external drive.

Fortunately I had a another SDD that I could use. I reformatted this and connected externally . Checked with file folder that it could be read and was empty. All good.

Used Macrium to clone but was concerned that if supposedly booting form 2 internal drives, what am I copying, and would it work?

It didn't!

Both drives had 3 partitions; An EFI System partition (100MB), Windows 11 Home partition (465 GB) and a Recovery Partition ((610MB)

To cut long story short, the external drive now consists of 2 partitions, The EFI partition and an unallocated partition.

The external SDD is no accessible !!. I get the message "You currently don't have permission to access this folder" and continuing, "You have been denied access to this folder" " to gain access to this folder you will have to use the security tab"

Don't understand what to do next.

Using Disk Management and right clicking on greyed out EFI partition gives a greyed out window

Can anyone help in getting this 'external' drive accessible again ?

    Mountvol command typed was incorrect.

    It's:

    mountvol y: /s

    Also, the command "detail disk" is missing.

    Moreover, run them from WinRE Command Prompt instead of admin Command Prompt.

    The drive letter assignment can change when you're in WinRE.

    Please run:

    mountvol y: /s

    diskpart

    list disk

    sel dis 0

    detail disk

    list part

    sel dis 1

    list part

    list vol
