Sata SSD not showing up in boot order

[WreckitRalph907]

I recently bought a 2TB Sata SSD (T-Force Vulcan Z 2.5 inch SSD) and did a clean install of windows 10 on it through the Windows Media Creation Tool. The SSD works and I'm able to boot into windows but only if I have the original hard drive that came with the pc hooked up. The SSD will show in the bios as being connected to the pc but it won't show up in the boot order or detect Windows on it when booting without the original hard drive connected. (When booting with both the original 1TB HDD and 2TB SSD, it'll show an option to boot from either the SSD or HDD)

That will happen if/when the original hard drive was present when Windows was installed.  Windows will put the boot loader on the existing hard drive and when that hard drive is not present,  the PC does not have any direction as it cannot find the bootloader.

You can do the Windows install again with the original hard drive not present and it should work OK.  Then you can reinstall the original hard.  You can then look in the boot order, F9, and chose which Windows to boot to.
