Add the unallocated 48GB to the D drive

Especially if you run reagectc /disable before deleting the recovery partitions. After they are deleted, the run reagentc /enable and you still have recovery environment enabled, it's just the files are under C:\Recovery now. I see absolutely no use for a recovery partition that is on the same physical disk as the Windows OS is on.

Now we are back on track. Chuff Chuff

Thanks Cerebus, the quote feature does no really work for me. So I do it the old way.

So I should keep Partition4 and can delete Partition6 , correct ?

> My only other comment (more my preference) is your C drive is a bit small

I am not sure I understand that. I hardly install any new software so I think it is unlikely this Operating System Partition will be too small in the foreseeable future.

Thanks for the response Glasscuter

> DO NOT mess with the reserved partition.

Ah ok, seems opinions come in various flavors

> I would like to ask a question though. What is your D: drive used for?

C = Operating System
D = Files

Yes, you can safely remove partition 6 i.e. far most right partition.

Re. C drive - it varies from person to person, but as I said, now you know how to move/resize partitions, this is something you can do on an as needs basis in future.

My goto program for disk management is Mini tool partition wizard, it works for me.

GeneralLee01 · Mar 21, 2022

I did the following

- reagentc /disable
- delete the partition I thought had to be deleted and extend partition D with that unallocated space
- reagentc /enable

But seems I do not have a partition marks with RECOVERY anymore, as I had in the screenshot in the first post of this thread. At least according to disk manager. The Mini Tool has a different opinion?!?!

Also . . what is that 16MB partition good for ? Is tiny, so don't need that space, but still, can I get rid of that ?

I now have the following . . . .

DISK MANAGEMENT

MINI TOOL PARTITION WIZARD

DOS PROMPT

Re. Recovery Partition, not sure why label is gone but still seems to be working ok

Re. 16 MB partition, this is a total mystery to all users. It is reserved for a future function which MS have never specified. It used to be 128 MB on W8 but was reduced to 16 MB on Windows 10. However presence of partition complies with MS requirements for a UEFI installation. In this case, it really is so small, it is not worh doing anything with. It does not even show in Disk Management.

Personally, I think it is only there now as nobody even in MS knows why it was there on first place and nobody can make a decision to remove it LOL.

What's really interesting is if you convert an MBR disk to GPT using Microsoft's own mbr2gpt tool - there is no MSR partition created! So, apparently Microsoft does not really require it on GPT disks like they claim in other documents.

I guess that is because you can only have 3 primary partitions to use mbr2gpt. It tries to create the EFI partition first and falls over if already 4. So I guess it deletes msr (only if four partitions?) to ensure only 3 partitions.

There would be no existing MSR partition to delete because you cannot create an MSR partition on an MBR drive. If Microsoft really needed the MSR partition, then the mbr2gpt tool could simply shrink the EFI System Partition by 16 MB and create an MSR partition in the empty space - after the conversion to GPT, of course. But it apparently is not that important to them.

Thanks Cerebus

So that means I can enable bitlocker again.

I have a pdf with the Bitlocker Drive Encryption Recovery key. Will that key stay the same . . . ?

Dohhh - of course - Brain not in gear!

I agree with your logic i.e. creating msr after gpt conversion would work, but as you say they do not bother.

I would love somebody in MS to expain why. Response would be probably in Emojish "

which for anybody over 14 translates to "Hmmm, no idea, don't go there!".
