How should I make two partitions with the Win 10 installer pendrive?

Hi all,

I plan to buy a Samsung 970 EVO Plus 1TB M.2 PCIe NVMe SSD, and I want to make two partitions on it at the drive selection screen of the OS installer like this:
D: round 800,0GB
C: full size which remains after the OS related (EFI-system, Recovery, MSR) partitions created (~130GB according to the 931,51GB usable space of the 1TB drive)
I have found a >>video<<, which suggests the following steps:
1. "New" - size: 134666MB (131,51GB) - "Apply"
Then the 3 OS related (EFI-system, Recovery, MSR), 1 Primary and a round 800GB unallocated partition will be created.
2. Click on the unallocated partition - "New" - size: full size that the installer offers - "Apply"
3. Format the bigger primary partition (I think it's optional, and can be done after OS installation via Disk Management)
4. Click on the smaller primary partition - "Next"

It seems to be absolutely fine for me, but on the msi forum, a comprehent member said and suggested the following:
"It is recommended to have "personal" partitions after the boot loader, you have to create it at the "end" of the drive (I known it is not physical end because it is a SSD, only logical).
That is why I suggested:
1. "New" - size: 134666MB (131,51GB) - "Apply"
Then the 3 OS related (EFI-system, Recovery, MSR), 1 Primary and a round 800GB unallocated partition will be created.
2. Click on the unallocated partition - "New" - size: full size that the installer offers - "Apply"
3. Click on the smaller primary partition - "Delete"
Then this partition will be unallocated.
4. Click on the smaller primary partition again - "Next"
Doing that, installer will create all required partitions for OS in the 1rst part of the SSD."

Which method should I do to make the best optimal way?
Thanks,

I would not go that small with a Windows partition. I would keep the Windows partition between 200~300GB. I use a 250GB partition for my Windows and I do not keep any of my personal files (that I intend to loose on a Windows 10 reinstall; if necessary) on the Windows OS partition/drive.

Keep in mind once you partition your hard drive and you start allocating the partitiions with data (especially Windows data) it is going to be a nightmare if you need to expand your main Windows partition if you need more space allicated for programs and other Windows functionality. You might have to move data off the second partition, move the partition and then replace the data back onto the second partition. Depending what the partition manager and Windows will allow you to do.
