Installation Issues, getting the prohibited sign at OS X Install

[SoupWilliamson]

Hello, trying to finish my first hackintosh build and have run into a brick wall getting OS X to actually install. I believe I have all the bios setting correct and have made multiple usb sticks with unibeast, all to no avail. I should mention I tried two different installs of Sierra on unibeast sticks i made and one of el capitan. All resulted in getting to the OS X screen with the install bar at the bottom for about a second before going to the OS X prohibited symbol.

This is on an Asus Maximus VIII Extreme Assembly with an intel i7.

There are a few Successful Builds with your MoBo or similar ones with EXCELLENT Steps that you may be able to use with your build if you check the Forum.

I have since tried many more things, including but not limited to, downloading USBInjectAll.Kext and nvidia config, both below. I added them to my usb stick in the proper places and got to the same symbol even faster. Still no luck, any ideas?

here's a video of my issue

can anyone tell me where my issue is? Since clover loads does that mean the boot loader is definitely good and I don't need to tweak that?

Is the issue 100% in the USB stick at this point and if so does the video above show my error?

By booting in verbose mode I got El Capitain installed, I got to it's install screen, formatted the drive, and installed El Capitatin. The system then rebooted and went into bios, it can not find any bootable drives and when I try to boot fro the USB stick it gives an
error allocating 0x12f5 pages at......
error loading kernel cache (ox9)

I just had a chance to take a look at your Config.plist. It shows your System Definition to be Mac Pro3,1 which does not boot. Tonymac post https://www.tonymacx86.com/threads/...acpro3-1-macpro4-1-system-definitions.200868/ says "Starting with macOS Sierra, Apple has decided to drop support for MacPro3,1 and MacPro4,1 systems."

Therefore, change your System Definition to iMac 14.2 and try .
Sorry I missed your attachment earlier and saw your long Video only and it was rather difficult to view clearly. I prefer static images uploaded to the Forum.

I noticed from Clover Install log , you have both your USB installer and System Disk with El capitan mounted. While using the Multibeast, could you have , by any chance, missed the target disk? Chose the USB Installer disk instead of HDD Sierra System disk for that Multibeast installation failure ?

See attached image where target can be wrongly chosen by oversight.

I suggest a repeat attempt to install MB 9.01 on System Disk at this point.

PS. To see your MB install log Launch "Console" [Applications>Utilities>Console] >/var/log expand to see Install log

Thanks for your help, i definitely installed on the el capitain disk, not the installer usb. I downloaded the new version of MB, 9.0.1, and got the same result. Installation failed.
