Hello there!

Few weeks ago i had a High Sierra machine working perfectly! Than i decided to try Mojave but it was a nightmare as my Intel HD graphics won't work at all so i decided to go back to High Sierra but it is impossible to get the USB thumbstick to boot the installer on my computer.

Sometimes the USB flashdrive would appear but will not boot at all saying it requires a boot device to work or it would not show up at all on the boot devices list, tried UEFI, Legacy, AHCI modes, VT-d disable/enable, XHCI and etc...

Also tried on different USB ports (2.0/3.0) and nothing would work, funny because on Windows the USB stick works perfectly with no issues at all

I have no idea on what's going on so i decided to come here and create this thread.

Here's a quick video of it and BIOS settings

My system:

Intel Core i5 4460

Gigabyte H81M

16GB = 2x8GB DDR3 HyperX

Nvidia GeForce GTX 970 4gb

SSD 120gb for Win10

HDD1 1TB for Games on Win10

HDD2 250gb for Hackintosh (previously with HS working on it)

Apple USB Keyboard and a Logitech G400S mouse

 

Any ideas everyone?

But i need to actually boot the USB installation for that right?

I can't get my USB thumbstick with HighSierra image to boot to be able to change igpu injectintel.
