566776, System Partitions
Posted by lenjack, Fri Dec-11-20 03:33 PM
Something I've been wondering about for some time. Just set up a new W10 build, on a freshly formatted drive. Why does Windows set up a 100 MB partition in front of my main partition, and a 505 MB partition, after it?

All I know it's boot files and no idea why it splits them up in 2 partitions. It usually called System, Recovery and windows.

Yeah, that's what I see too. I'm sure(?) there's a good reason for it. Hoping someone will let us know.

"On any UEFI / GPT machine, Windows 10 can automatically partition the disk. In that case, Win10 creates 4 partitions: recovery, EFI, Microsoft Reserved (MSR) and Windows partitions." It's a Win10 thing.:rolleyes:

I realize that it's a W10 thing. I don't have 4, I have three on my 500 GB drive. They are as follows:
----------------------------------------------------------------------

100MB Healthy (EFI System)

(C:) 476.33 GB NTFS Healthy (Boot, Page File, Crash Dump, Basic Data
Partition)

505 MB Healthy (Recovery Partition)
----------------------------------------------------------------------
I'm just wondering why Windows does it this way.

You may have 4 - as I do - but one may not have been assigned a drive letter.

Right click your "Computer" desktop icon and select "Manage". On the window that opens, scroll down to and click Disk Management (under Storage). If you have an unassigned fourth, it will be displayed both in the list and graphically.

If you do, you can assign it a drive letter if you want/need to.

That's exactly what I did, and the three I listed are all that appeared.

How does the system run?

Fine, except see my other new topic.

This is what I have and I am betting I could merge the last partition with the unallocated space with no problem and end up with your three partitions. How it ended up that way is a question. I do know win10 Home will let you do that but Pro may not. The recovery partition has what it is necessary to reset windows. It works with System Protection that I am pretty sure uses your main partition for restore points, but I may be wrong.

My W10 is home edition. I'm just curious. I don't plan to make any changes.
