BootUP Error on New PC

[Waqas409]

So i changed my PC and when i plugged my existing Harddisk in the new PC, At first it does not let me boot.
Says the following error shown in the picture.
Then in bios Drivess section i changed to "ATA" now it does work but im still getting this error, everytime i start my PC i had to press F1 to continue.
Is there any way to fix this?
Thanks

NO.
I only have 1 hard disk installed in it. 

However on motherboard my hard disk was not Booting up on "ATA" Mode on that BLUE COLORED Sata Socket.
Its working on Black one but i dont know how to fix that error.
