    BIOS sees new HDD but Windows Device and Disk manager do not

    I just bought a used, rebuilt i7-3770 computer with Toshiba 1TB HD (SATA0), 16GB memory and Windows 10 Pro in a HP 8300 Elite case, with HP motehrboard. I bought a 500 gb Samsung SDD. I installed it on SATA1 and BIOS showed it. Then I tried to clone to it and both clone softwares and Windows 10 Disk and Device Manager would not see it. So I put it in a USB adapter and cloned to it with no problems. Then I installed it in SATA0 (unplug HDD) and it boots just fine. Then I installed the original HDD again on SATA1, BIOS sees it but Windows 10 does not. So I unplug the SSD from SATA0 and reboot and it boots fine from the HDD from SATA1. So both drives are recognized and boot when they are the only drive installed. So I plug in the SDD to SATA0 again and it boots fine from SDD, but no HD on SATA1 in Windows. So I change the BIOS to boot form SATA1 on HDD. It boots fine from the HDD on SATA1 but no SDD on SATA0 in windows (BIOS sees it). So the cables are good. The connections are good. Both SATA0 and SATA1 will boot when selected or only drive connected. BIOS always sees both or either drive when connected. But it won't show both drives in windows Disk Management or Device Manager when both connected. They always show the on it booted from and that is it. What do I do? Is there another BIOS setting I am missing?

    SOLVED! Deleted ATA controller in Device Manager and rebooted. It found both drives when rebooting.
