[SOLVED] Win 10 boots from SSD but when HDD is connected, computer won't boot

[BrianRegrut]

When HDD is connected via a USB connection, it boots fine, but when placed in computer and connected via SATA cable, reboot doesn't complete. Drives seem to be in boot order. There are NO system files on the HDD.

HP Compaq 8200 Elite Convertible Minitower Business PC

I have tested all the SATA cables, alternated the ports and the power connections.

Ok.
Can you show photo from BIOS boot order settings?
Connect 2TB drive with sata cables first.
2TB drive should not be listed in boot order.

Also, since OS is installed in legacy mode, you should disable UEFI boot in BIOS.

Thanks for your help. I've had to leave my office for a couple of days and will try your suggestions when I return.
