I was told my motherboard was bad and needed to replace. I bought the exact model motherboard with new processor. When I hooked everything back up and boot I receive the message Missing operating system.  The bios recognizes the two Sata hard drives. I have tried telling it to boot from Sata 1 and sata 2 and get the same message.  Have flashed the bios as we'll. Any help would be appreciated

pls share the motherboard make &model number.
In BIOS change the "SATA controller mode" to AHCI, if already selected then change to other mode.
press F9 or may be F10 and select the boot device one by one.

Boot From Your original Windows 8 DVD

Insert a Windows 8 DVD, boot from it.
 
From the Windows Setup screen, tap or click on Next.
 
Tap or click on the Repair your computer link at the bottom of the window.
 
Advanced Startup Options will start, almost immediately.

Please see below, May be it will help you.

* Simple BIOS auto-recovery process
The CrashFree BIOS 2 feature now includes the BIOS auto-recovery function in a support CD. Users can reboot their system through the support CD when a bootable disk is not available and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

Maybe it wasn't only the mainboard that was broken, but also the disk? Test it using the manufacturer's diagnostic utility, which you'll find on the UBCD:

When booting from cd on either hard drive I receive the message that your PC ran into a problem and is restarting and it restarts and the same message again.  I have only one hard drive plugged up at a time.

see if "UEFI and Legacy mode" is showing in BIOS. Try to change it.

If you had Secure Boot turned ON on the old system, this will cause a boot issue.  That's because the Boot Sector has linked itself to your old motherboard and made it so you can't just remove the hard drive and throw it in another computer to boot to it.

You will most likely need to re-write the boot sector for your OS if you want to get back up and going.

I've used this answer several times on OS boot issues for Windows 8.

Go down to the answer that starts with "I've spent a lot of time trying to get my Windows 8 PC to boot again".

It was the raid controller setting in the bios. It works great now.
