startup.nsh problem on boot

view story

http://ubuntuforums.org – Hello, I have a system with UEFI and windows 8 pre installed. I have installed ubuntu 13.04, and Grub is showing up now, I was having an issue where I couldn't get it to boot into grub, however that error is fixed. Now, sometimes while booting (It seems like every other time, then I hold the power button to turn off and then turn it back on, and then it loads up into grub) it will show up a black screen that looks like this(This is not my PC, but the error is what appears to be the same) It counts down from 5 saying to skip startup.nsh, it may even say there was an error loading startup.nsh.
