Windows 10: Diskpart - remove drive letter, but returns on reboot / Recovery Parti

Hi there,

This is the first time I have posted here. Hi there everyone.

Windows Version Number: Windows 10 Pro - v 1909.

My laptop has been experiencing a problem. At the root of this is a damaged parition table - but I have had to do more than this - and no OS can be found as it is divded over two drives C: and E: which is a ramdisk created by the recovery process in response to the partition table corruption.

However in using TestDisk by way of only a test. My recovery partition has been slightly changed whilst I actually did nothing to it. The recovery partition is nolonger hidden and now has a drive letter f:. What I am trying to do is return it back. I can easily hide the partition by giving it a 'set id 27' in diskpart. But if I 'remove' the drive letter in diskpart it does go only to return on every reboot. My question is how to permanently remove this drive letter, any idea of the practices used by the manufacturer to achieve this? I want to reconfigure it just as it had been set up. (I have got another solution, but wanted to ask before I try this one). The aim is to get ... bcdedit /enum all ... to state the same that had listed the hidden recovery partition in one of the windows boot loader entries. This partition might have related to the creation of e: the ramdisk? (I am aware winre / winpe can create this).

Then I want to make sure the recovery partition is correctly configured and if it still is playing a role in the recovery process after all the updates of windows made in the past. For this I am aware I need to use reagentc.exe. But is this just a case of establishing the paths to the files install.esd and winre?

Any ideas?

:)

Diskpart - remove drive letter, but returns on reboot / Recovery Parti

Hi TroubleShot, and welcome to Ten Forums.

You could try other methods of removing drive letters, but I would like to know a bit more on your system situation.. What happened that broke your system.. etc.

Anyway, here is Tutorial on How to remove drive letters (by Brink). Try 3rd option:

in elevated command, assuming your recovery partition is F:

Back to your trouble... I would make an Image of your drive, just in case anything goes wrong, and do a Repair install with an In-place Upgrade (mounting Windows 10 ISO and upgrade your system )

 

Power Outage or Reboot Resets Drive Letters

Thank you for the reply, but I would like some clarification on the suggested solution(s).

In running diskpart, I typed "LIST VOLUME" as suggested by Rover85. I noted that my D: drive is listed as volume 8 and my E: drive is volume 9.

Do I then continue in diskpart with Gavin Adams answer of 1/27/2013 with the following script?

LIST VOLUME

SELECT VOLUME 8 (and/or 9)

ATTRIBUTES VOLUME CLEAR HIDDEN

EXIT

And this will assign the appropriate drive letter on reboot?

The one thing that bothers me is that my first try after reboot with Computer Management/Disk Management would not connect to the "Virtual Disk Service" until I did a second reboot.
