Windows 10: Hide system partition that shows in explorer but NOT disk management

After installing Windows 10 (upgrade from 8.1) and after a second reboot, the 100MB "SYSTEM" partition shows up in Explorer as the f: drive. It cannot be hidden in Explorer - "Hide Selected Items" - prompts for administrator permission then Error 'the parameter is incorrect'.

In Disk Management the SYSTEM Partition does not have a drive letter assigned, and ALL options are greyed out.





None of the solutions I have found work, seemingly because the partition does not appear as a drive letter to the OS, only to Explorer. How can I hide it?

Empty partitions?

You may need to show hidden files. Use the keyboard shortcut Win+X to access Control Panel, File Explorer Options and select View, Advanced Settings. Verify that the box before "Show hidden files and folders" is checked and "Hide protected operating
system files" is unchecked. You may need to scroll down to see the second item. You should also make certain that the box before "Hide extensions for known file types" is not checked.

 

windows 10 file explorer duplicated my partitions i have 2 sets of every partition

i used computer management to re-assign drive letters to re-arrange all my partitions in file explorer

now under this pc i have all my drive letters correct the way i want them when i go into file explorer

it has duplicated all my partitions made 2 sets of all my partitions the correct set of partitions is under

this pc but file explorer still lists the old set of partitions

how do i get rid of the old set of partitions in file explorer

computer management shows the correct set of partitions that is under this pc

but in file explorer it shows 2 sets of partitions

how do i get rid of the old set of partitions

 

Can you show a screenshot of File Explorer?
it is usually impossible for a drive to have a letter in File Explorer but not in Disk Management.

 

A drive letter being present in File Explorer but not in Disk Management is a known weird side-effect of installing Windows 10 upgrade over a Windows 8 installation that was created using some "disk cloning" software. In particular, this effect is known to take place if the Windows 8 installation was created with Paragon HDD-to-SSD migration software.

Paragon software works fine in general, but still they are doing something wrong, which reveals itself when trying to upgrade a "cloned" OS to Windows 10.

I had the same issue and I found no credible solution for it, aside from clean-installing Windows 8.1 directly to SSD from scratch and then upgrading it to Windows 10.

 

• Open Admin Command (Win+X->Command Prompt (Admin)) then type:
• diskpart
  list volume ====> look for the Volume # that has the size of 100MB
  select volume # =====> # found from list above
  remove
  exit

This should remove the letter for the 100MB EFI System partition.

It's a glitch with upgrade.

 

This worked perfectly.

Many thanks Topgundcp.

For info: the NoDrives Registry entry did not work in this case.
Also, this was an Asus factory install of OEM Windows 8.1 so there should not be any ghosting software involved outside the factory.

 

That is correct, but the factory does clone these disk in bulk...

 

Yes, of course .. I just made the comment for people like AndreyT who are interested in particular cloning software, to draw their own conclusions as to the source of problems on other machines. It was no accident that I used the words "outside the factory".

 

I used the diskpart solution only for the partition to be displayed in windows explorer a few days later again *sarc

 

Hello,
Or you could simply, from within disk mgmt., select the partition, right-click, change drive letter & hit the Remove tab.

 

This worked for me too, but upon reboot the system again lists the ESP partition together with the drive letter under my computer. Is there a way to make this adjustment permanent? Here is a screenshot from My Computer and diskmgmt.msc

 

The real solution is deleting the corresponding key from the registry as below:

• Open RegEdit

Start -> Type "regedit"

• Navigate to

Computer\HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

• If the EFI partitions drive letter is still in registry, delete the value.

For example: \DosDevices\G:
