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 ?

    Hi Remesh,

    The reason for zero response from me in last few days is days is because not been feeling well. A lot better now.

    I've taken your advice and removed Drive 1 (MS) M390) and, lo and behold, the system has booted Drive 0 (Samsung EVO).

    If it did, you recommended to clone Disk 0 to Disk 1 and then detach Disk 0. That will be my next task.

    Having detached the Samsung you recommend that this is used as an external cloned device rather than internal ?

    Or, you may try this.

    Under BBS Priorities,

    • Choose "UEFI CD/DVD" (or anything other than the MSI disk) in Boot option #1
    • Choose Samsung SSD 850 EVO in Boot option #2

    See if the system boots from Disk 0 (Samsung SSD) now.

    Hi Remesh,

    Snipping working again.

    This is my boot configuration. As we know, booting from Disc 1 (MSI M390); Boot Option #1. I don't see in any of the other boot options reference to disk 0 ()Samsung EVO)

    I've included UEFI disc priorities. Can't say I understand what these mean but I note both boot option #1 and #2 have the MSI M390 (disc 1) as the boot drive (?)

    You ask to disconnect disk 1. This is not easy as fixed to the mother board with tiny screw. I fear I might cause damage in attempting to remove. If you don't think there is any other option, I might risk it.
