Windows 10: Think I finally have my boot drive squared away

RIch, you might want to also do a screen cap of diskpart, select disk 0, list par while you're at it to supplement the easeus info.

 

Diskpart doesn't show anything useful that I can see:

Code: >diskpart Microsoft DiskPart version 10.0.10586 Copyright (C) 1999-2013 Microsoft Corporation. On computer: DESKTOP DISKPART> sel disk 0 Disk 0 is now the selected disk. DISKPART> list par Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Recovery 450 MB 1024 KB Partition 2 System 100 MB 451 MB Partition 3 Primary 232 GB 551 MB[/quote]

 

OK. thanks - sorry, I meant more like when you first clean install (if you do that) and also a little bit because I don't know easeus and wasn't sure it would show an MSR (but I shouldn't be that skeptical).

 

diskpart
select disk 0
select partition 1
shrink desired=16
create partition msr size=16
list partition

I think that is what you need.....

 

Doesn't work:

Edit: Should I shrink C: (partition 3) then create the MSR?

 

Use Win10PESE and use aomei partition assistant to shrink that partition 1..
then use diskpart to create MSR partition

 

Why shrink par 1? Shouldn't MSR be par 3?

 

He could shrink C 16MB and then move to right - to open space for par 3 MSR..
that would give the proper layout..

he could use diskpart and shrink C - but MSR would be last partition

 

Understood and that's why I questioned par 3 versus par 1, i.e., with MiniTool in the mix (safe to assume easeus can do same), shrinking C and moving it right 16 MB seems the ticket for opening the MSR hole in the right spot.

 

Just a silly observation here...but isn't the computer in question working just fine without the MSR partition?

 

Yup, working just fine so I guess this is a feel good operation.
Surely with the attention to detail you've shown you can understand why I want this to look right, even if it doesn't make any functional difference?

What am I missing if I don't have the MSR partition?
What won't work.

So far, I've not found anything that was not working correctly.

 

Just because Windows creates something automatically does not mean it is "right". What is right to me is that everything works the way that I want it to with the setup that I want to have.

The MSR appears to be free space that will be farmed out for future changes to the drive's partitioning:
Windows and GPT FAQ - Windows 10 hardware dev

My feeling is that I am not planning on changing the way my current system operates regarding the disk partitions, so I don't feel the need to keep the MSR on it.

This statement from the same link:

Is obviously false at this point in time. I've got two laptops with UEFI bios and GPT disks that run just fine without the MSR partition - and seems like yours is/was running just fine without it as well.

Now, that being said, there have been people who have had upgrades to Windows 10 fail because their System Reserved partition (not to be confused with MSR - two different partitions) were too small and they had to use something like MiniTool Partition Wizard to make room for and expand the System Reserved partition. So my feeling is if at some point I discover that Windows complains about not having Microsoft's precious reserved disk space, I'll make it when I am forced to.

 

You actually only need the EFI partition and C Drive partition as a minimum.
