Setting partition size when installing Windows 10 2004

Topic

New Reply

When doing a clean Windows 10 (2004) install, the installation creates 4 partitions:

100 MB EFI FAT32,

16 MB MSR,

xxx (pick a size) GB Windows C: NTFS and

600 MB Win RE NTFS

I want to change those sizes, and after doing SHIFT-F10, diskpart, clean I am presented a pristine disk.

I cannot create the MSR with the Windows install routine, so I make a 260 MB FAT32 partition for EFI, a very large one for Windows 10 C: and 1000 MB for Win Re.

BUT then Windows creates a SECOND FAT32 partition and after that the MSR partition.

I don’t want 5 paritions, 260 MB FAT32, then 100 MB FAT32, then MSR, then C: and then Win RE.

I want ONE 260 MB FAT32, then MSR, then C:, then 1000 MB Win RE.

Why doesn’t Windows 10 installation offer any help in doing that?

The same reason why it doesn’t allow users plenthora of other optional things like controlling updates, GUI customized to your liking etc… They think they know better what’s good for you than yourself.

Why exactly do you need 260 MB EFI FAT32? Or why isn’t it good to simply put all of these into one partition that fills the whole system disk so then Windows forced to put all of them into separate folders in the system drive?

Did you create your 260MB partition as EFI?  In other words,

DISKPART>create partition efi size=260

There is also

DISKPART>create partition msr size=512

And for your Windows partition

DISKPART>create partition primary size=xxxxxx

DISKPART can also format each of those after you do a “list vol” command, then “sel vol” followed by the volume number as listed, then use the format command.

DISKPART>format /? will list the proper syntax for formatting.

Always create a fresh drive image before making system changes/Windows updates; you may need to start over!

We all have our own reasons for doing the things that we do with our systems; we don't need anyone's approval, and we don't all have to do the same things.
