Start up problem with Mpower Max AC

[martijnvkk]

Hello,

I got an Mpower Max AC motherboard with an i7 4790k, H100i, Samsung 850 Pro 256GB, and and HDD 1 TB, Corsair RM 750 and Kingston DDR3 1333Mhz.
I started up but i got no signal, i connected it with an HDMI and i tested the HDMI. I also got the Code in the right bottom corner of A2.
Hopefully you guys can help me.

EDIT: I just fixed it by changing SATA cables, now i got the message: Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key

Hi,

If you're as far as Reboot and select proper media device, then that means you have to install OS on a HDD now

When your system is booting, press F11 to enter boot menu, then select the HDD with OS or select ODD or USB to install OS.
