First I replaced my h81 mb to a Z97 deluxe to be able to OC my i7 4790
After I replaced and everything went smoothly I have noticed to an issue , when I start my machine it says that "operating system wasn't found".
After it I thought it's because I swtiched mb and I didn't really care to format cause I didn't have a lot of thing on my PC.
After it I have noticed to another issue , my PC recognizes one of my two hdds but doesn't let me use it so , I created a new partition and it worked , now I restarted my PC and it says again that "operating system wasn't found" please help me what to do, I tried to unplug one of the drives to start from my second drive but it keeps saying that
 
Solution
with second hard drive use windows disk tools/disk managment to see if it sees the hard drive. if not may be a bad drive sata cable or power.
with windows 10 you start from a working pc download windows 10 from the media creation tool. in the bios set the boot order to usb. install windows then go back set the boot order to boot from hard drive in boot order. make sure sata ports set to achi not raid or ide. on newer zmb there may be intel and acmdia sata ports make sure your on intel ports 0/1
