Before i go for fully clean install,want to try here for help because i cannot seem to solve it

After i changed my Z68A Mobo CPU and Ram TO Skylake build Asus Z170-S TUF and i7 6700k,my SSD and HDD remained same,i plugged everything together and everything worked fine but after a little i noticed insane long BOOT UP times like 25 sec from 8 sec (old setup).
I cannot BOOT from my SSD if i choose First SSD then Second HDD it says BOOTMGR. missing.If i Choose HDD first system boots.

What i tried so far is AHCI mode (by default AHCI)
Insert cable in different ports
Any help is greatly appreciated 😮

Looking foward to your reply

Hi Streamroller

When upgrading to a new motherboard you always want to do a fresh install of windows.

Do a UEFI install on your ssd, once windows installs select "windows boot manager" as boot priority 1.
