Hi
I have a two laptops with Windows 10 x64. Recently I noticed new partition with next available letter. Size is 128mb and it can't be accessed. I checked in Disk Management but this partition is not listed there as per the below screen:
I used MiniTool Partition Wizard and managed to see details about this partition.
I tried Diskpart to remove Drive Letter but no luck:
This happened at the same time on my two HP laptops but not sure what could cause it. Maybe some Windows update? I do not remember installing any new apps. I would like to remove this disk from the list of available disks.
Can anyone suggest/advise how I can remove this from the list?
Thanks
You never selected the volume so you can't remove the drive letter assignment - that's what the command response tells you. do a "list vol" to show list of volumes and confirm its volume number then do "select vol ___" (insert volume number) to put focus on that volume and then "remove" should work....

This appears to be your MSR partition (apparently created in Win8/Win8.1 install before upgrading to Win10). Should not have a drive letter at all.
Do you know that you are booting OK in UEFI mode ? It certainly looks like you have a GPT disk, although it's a bit mis-mashed due to upgrade process.
The subject was already previously discussed.

Dont' see any discussion of a drive letter having been assigned and how to remove it at that link, whs - however, it does answer a bit what MSR is.The subject was already previously discussed.

BTW, welcome to windowssh blog, Kruk.
Furthermore, Disk Management will NOT show the MSR partition, whether it has a letter assigned or not. whs's link reminded me to point that out to you.
Hi
Thanks for the comments. I have seen this link before but as you mentioned this can't be applied to my case as there is nothing about the letter assigned to the partition.
About the Diskpart - I tried the "list vol" but the 128mb partition was not on the result list. I will provided the print screen tomorrow.
As far as I know the booting is working fine. Is there any way to check the UEFI mode you mentioned?
If boot appears fine, that's good. I was more looking to confirm you were booting UEFI. In fact, I should have just asked you to do this, from command prompt or run box: "msinfo32" and report the entry displayed on the "BIOS Mode" line - should say "UEFI".Hi

Second thought - it should display that partition, however, in diskpart if you do "list par". here's how mine looks:
(Note partition 3, 16 MB MSR is size created during my Win10 clean install)
OK. I will check it in the morning.
Easiest thing to do is delete the msr partition as not really needed.
You can recreate it using diskpart commands.
Also, you could backup the 20 GB recovery partition as it is no longer needed really.
I have a 128 MB partition but it is labelled 'Other'. However, i also had two partitions that had drive letters assigned to them - one 601 MB at the very front of the drive and a 452 MB one at the very end of the drive! With the help of 'Word Man' and others, i decided to format both of them and now they are seen as 'unallocated' - i'm not going to worry about a GB of space on a 500 GB drive!
