boot message

Hello forum, I have this annoying flash on my screen for just about a second, as soon as I select the boot drive option on my GB, I get this flashed, and the boot continues. Does this message mean anything useful, and if not, can I simply disable it? Please advise,

So just got a Gigagyte b75m-ud3 with uefi bios, installed everything perfectly with unibeast and mountain lion, everything is working fine. ....EXCEPT everytime I boot there's this "BOOT FAILURE"message from bios. I don't know hot get rid of this, because i have any problems at all with boot...
