This hanging usually means its detecting a device plugged in. Remove all devices should be fine.
Right seems like it was the Samsung evo 850 SSD that was causing it to hang. I disconnected it and it went straight to Bios.
Im running the Samsung m.2 on a asus hyper adapter as main drive and the SSD as my games drive.
Is there anything i can change to make it boot to bios without me having to disconnect the drive every time?
p.s Running 4.12Ghz no problem. will try next stage!
