I connect with Displayport, followed JL and iMike's guide, and all work great now! Thanks a lot!

Thanks for your help, Jake Lo and iMick. I'll test DP to DP connect before buy a DP-DVI adapter. It only can boots from USB, when booted, I choose run the OS X from HDD, comes a restart.

DELL 9010DT Specs: i7-3770/8GB Ram/HD4000/500GB HDD 1,Build USB Installer with myHack with generic Extra folder 2,Extract Extra - Opt9010 folder to USB 3,Boot with USB Installer (VGA is not supported? 9010DT HD4000 Doesn't have a DVI or HDMI! ) VGA is OK to run... 4,Select "Use My Own" and point to Extra - Opt9010 5,Select Yes 3 times to delete issue kexts 6,Install Failed at the end! OS X could not installed on your computer. Ignore Install Failed error and restart, then...could not work ...boot with USB only... any suggestion?

So awesome! Thanks for your manual!
