I tried to use this command to see the content of my EFI partition

I found this result online and the writer said to use this command in Powershell:
start ((Get-Partition | ? IsSystem).AccessPaths[0])
It opened up a windows explorer window supposedly showing what was inside the efi partition but there is a dialog saying "you do not have permission to access this folder, click Continue to permanently get access."
I clicked COntinue and after a few seconds there was a new dialog that said it failed and I need to go to the security tab to gain read access. So I went to the properties window but there was'nt even a security tab, so How do I gain access now?

Hello @Underscore77-2545

First, do you have admin rights on the system ?

If Yes, First open an elevated command prompt and give the EFI partition a drive letter, you can do it with mountvol or with diskpart.

I am doing with diskpart,

In the following example the EFI partition is on disk 0, partition 1 and will be assigned to letter b:

diskpart
list disk
select disk 0
list partition
select partition 1
assign letter=b
exit

Now kill the File Explorer process and start it with administrative privileges:

taskkill /im explorer.exe /f
explorer.exe

Now you can access the EFI partition with File Explorer.

Note that the EFI partition is a FAT32 file system partition. FAT partitions don't have the Security tab, this is a NTFS feature only.

What problems are you having that you need to view the contents of the EFI partition?

To view the contents of a partition it is usually easiest with free third party software with a right click.

For example: Minitool Partition Wizard, Disk Genius, etc.



If you need to use Windows commands then see if these steps work.

Open administrative command prompt and type or copy and paste: (comments are in parenthesis)

mountvol W: /s

(this should label the EFI partition with the letter W)

W:

dir

I just want to see what's inside out of curiosity. I will be cautious with this since these are the critical boot files of the system.
