    If you have trouble reaching the installer, type -x at the Boot screen as shown below. You can type the boot flags GraphicsEnabler=Yes, PCIRootUID=1, maxmem=4096, maxmem=8192, and npci=0x2000 by themselves or together in order to solve boot issues for older graphics cards and machines. Type -v to bypass the Apple boot screen and enter verbose startup mode. X58 and X79 systems always need npci=0x2000. For further explanations of boot flags, check out the post here. Also, if you need help with what to use for your graphics card, see the post here.
