Normal Drive Numbering Order

I just upgraded from a M.2 SATA to M.2 NVME primary drive. I also have a SATA SSD for storage. Prior to update my C: (M.2 SATA) was Drive 0 and the SATA SSD was Drive 1. After upgrade, the SATA is Drive 0 and the M.2 NVME is Drive 1. I tried unplugging the SATA but the minute it is plugged back in it goes back to Drive 0. I read this may be normal though and that SATA will take precedence over NVME in drive numbering. I just wanted to confirm this is true or, is there a way to re-number drives.

It's possible that this may depend upon the specific system (not certain), but I can tell that you cannot change this.

In my system, SATA is enumerated before NVMe, just as it is for you. As a result, my Windows drive is drive 4.

It is perfectly fine and normal to have windows on a drive other than drive 0.

@mccnavy

The SATA drives are numbered first. I've seen LOTS of folks comment on that.
Just like @hsehestedt said.

Much appreciated and quick responses. Thanks.

Booting into windows shows sata ssd as disk0 and nvme as disk1.

Booting into winpe shows nvme as disk0 and sata ssd as disk1.

I don't know why pnp enumerates the disks in a different order.
