DZ77RE-75K: BIOS has detect unsussful POST attempt(s)

The Board has the newest BIOS version (0053).


I have changed an external drive. The system was working fine with a WD "My Book" on Firewire. Now I have changed to a new WD "My Book" connected via USB3.0. The system start fails with the message:

The system BIOS has detected unsuccessful POST attempt(s). Possible causes included recent changes to BIOS Performance options or

recent hardware changes. Press 'Y' to enter BIOS Setup or press 'N' to cancel and attempt to boot with previous settings.


I have to disconnected the drive to boot the system. What I have to do for booting with connected drive?
