I added the file FakePCIID_XHCIMux.kext to the USB boot drive's clover>Kext>other but nothing happened, I don't know if I should install the boot loader to the drive itself and add it there, I don't think is going to make a difference. what do you suggest, and thanks for the help, I've been dealing with this for over a week now, is driving me mad, the funny thing is that I have a laptop with the same specs that my wife uses and is running apple's latest and greatest os and for some reason I can't get this install to recognized the sata controller or have the laptop's screen working, right now I'm able to see it because I have a external monitor connected to it.
this is what happens before the screen becomes garbled when booting from SATA
