One is an SSD, the other one a common plate drive. How can I tell which one is the SSD when installing Windows? My BIOS lists the SSD as P2 and my mech as P1, but that helpful distinction vanishes as soon as Windows 10's installation begins.
I'v gone through two installs and have gotten it wrong twice. It's aggravating.
If there's 2 drives during install, windows will inevitably decide it needs to be on both, so you get some files on one drive, some on the other. Kinda puts a serious damper on windows running at ssd speeds when it's constantly accessing the hdd too.
Just pull the Sata data cord from the hdd, no need to totally physically remove it, so that the ssd is the only drive recognised in bios.
