There should be no "prepping" of the drive. The drive should be blank when you install it. Boot from the Windows 10 USB flash drive, select the Custom Install option. On the next screen you should see your SSD listed as one big unallocated space. Click ont he unallocated space to highlight it and click next. What "prepping" of the drive were you referring to?
I was referring to this screen where you are asked which partitioning system must be used. Or is this only when initializing a new disc from inside Windows?
GPT would be more in keeping with Windows 10. Performance wise it doesn't matter.
What’s the Difference Between GPT and MBR When Partitioning a Drive?
Thank you all!
So in summary, I will set up this Win 10 NVMe with UEFI - AHCI for SATA & GPT. :)
Note also here -- MBR drives are limited to 4 partitions -- don't use "Logical Partitions " --they are a pain.
This could be of importance if you "Dual boot" OS'es from the same drive -- you might have 2 Windows systems or a Linux system so the limitation on the number of partitions isn't just of "theoretical interest"
GPT drives -- no limit.
Performance difference -- nothing even remotely detectable -- can't see why there would be - for the same bit of Disk hardware - once the OS has loaded it's all down to the OS'es kernel and the underlying file system(s).
