My current PC:
CPU: Intel Core i7-6700K ++ ARCTIC Freezer 13 CO
MBO: ASROCK Z170 Pro4S
RAM: 2x8GB Crucial DDR4 2133MHz
HDD: Samsung 850 EVO 250GB ++ Samsung SSD PM981 512GB M.2 ++ Seagate 2TB Barracuda 7200
VGA: Gigabyte GTX970 4GB G1
PSU: EVGA 650W GQ
OS: Windows 10 Pro

Although still working my Seagate HDD reports diagnostic errors so I wanted to replace it before it stops working. I got WD Red WDREDEFAX9 4TB to replace it but it seems that I'm not able to do it.

Current disk setup is:
- Samsung 850 EVO 250GB - system SSD disk with Windows 10 Pro installed and few other software
- Samsung SSD PM981 512GB M.2 - SSD disk for software and gaming
- Seagate 2TB Barracuda 7200 - storage only disk

When all 3 disks are connected to Motherboard and PSU everything works fine. When I try to disconnect the Seagate HDD (which is NOT a system disk) I get "Reboot and Select proper Boot device" error.

what I tried to do:
- to replace old HDD (Seagate) with the new one (WD Red). Same cables, same SATA port. I get "Reboot and Select proper Boot device" error.
- to disconnect the HDD's and leave only SSD's. Same error.
- I tried all the combinations with disks, cables and SATA ports... different disks to diferent cables to different poorts. Same error.
- while restarting the PC, using F11 to manually select my system disk (Samsung 850 EVO) as boot device. Same error


- to change boot option priorities in BIOS. Although the BIOS clearly recognizes my system disk (SATA3_2)

while trying to change boot option priorities I can only choose my M.2 SSD (Samsung PM981) and my DVD-ROM. There is no option to choose my system (Samsung 850 EVO) disk


- I restored my BIOS to default settings by removing the battery. Same error.
- I updated the BIOS to latest 7.50 version. Same error.
- I'm running out of ideas

The only way I was able to run my new HDD is to connect it while my old HDD (Seagate) is still connected.
Basically, what happens is that when I disconnect my Seagate HDD (which is NOT my system disk) I can't boot my PC.

At the end the problem was not in motherboard/BIOS

Although the windows were installed on Samsung 850 EVO, while installing, the windows created a boot/recovery partition on Seagate HDD of which I was not aware.

If someone has a similar problem, it is easily solved using EasyBCD software: [URL=https://www.sevenforums.com/tutorials/209885-bootmgr-move-c-easybcd.html]LINK[/URL]
