try rolling back USB kext, assuming your using thumb drive. USB errors. Can make small sata partition for installer instead as possible work around too.

    • Hi,Bergui.  I am certainly happy you finally solved your problem  but I am confused.  What you did is what you were supposed to do to do to begin with.  What were you doing before? You mean you were creating your USB with something else than a Mac? 
    • Is there a simple guide somewhere that explains what to do to to help out testing your ssdt's? I got clover configurator, ioregexplorer and some basic knowledge but it's hard to find out where to start.  Also... if I was about to apply an ssdt... is it easily reversible or do I have do an reinstall every time I screw up?   Edit: Admire your work by the way. I've been google'n this for years. Hat's off! 
    •   Hi Maldon, great guide! I got my old Dell 780 (LGA775) running High Sierra 10.13.4 nicely, thank you!   I have no audio and I see where you mention "Device HDEF + AppleALC + Lilu". I have AppleALC + Lilu in my KEXT folder but not sure what "Device HDEF" is. 
      Also when it goes to sleep it takes like 2 minutes to wake. I have a Q9400 quad core + Nvidia Quadro FX580 but don't have a DSDT for it. Can you help me with a DSDT?   Here are my RunMe Results https://drive.google.com/file/d/1Duv3XYyW4UhziDVVWdquwxYcGQ-D5tvm/view?usp=sharing   SPECS: Dell 780 MT, Q9400 2.66GHz Core2Quad Core, Nvidia Quadro FX580 
    • I've tried these several methods of booting into clover, but it still skips. I even double checked that i was using your Clover folder. Bios settings should be the same too... this is getting really strange here.
