Question Pc regonizes drive, but refuses to boot it

[FordFiestaZetec]

I have a pc That was built from multiple pc’s, i have a MP motherboard with an i5 3330 and 16 GB ddr3, and a GTX 960, there is also a 250 GB Crucial SSD installed, together with à 1 tB WD Blue
When booting the computer, it shows the bios Screen and the goes to the Standard reboot and select proper boot device Screen, when going into the BIOS
It regonizes my 2 drives, but at the boot section, there is no HDD to choose from.
Is this fixable without a Windows Reinstall?
this was all After the Power was off for a little while

With more than one drive in the system you'll have to go into the BIOS and manually select the drive boot order so the boot loader knows which drive to look at for Windows.

After the motherboard boot order is resolved and you can boot to the Windows desktop...assuming you are running Windows 10 you should run the option to do a clean reinstall if it's not the same motherboard Windows was originally installed on.

The windows 10 installation was installed on this System,
my Problem is that there are no drives at the Boot Order Screen, even though they Show up on the Sata Id screen
