My DQ77KB stops booting if 5TB USB Seagate drive is connected. The details are the following:
Is seems to me the MB tries to boot in UEFI mode when HDD is attached although UEFI boot is disabled in BIOS. What makes me think so is that just the same thing happens when I select force UEFI boot in BIOS with no Seagate drive connected. (But that might be just a coincedence).
Any idea on this?

I have noticed you are currently operating under Debian.
Does this problem occur on Windows environment?
Have you checked booting up with another computer and the driver connected?
