When I have Legacy Boot Roms disabled HS boots normally, it's just that weird graphics glitch at the beginning.

Hi Jake, when I enable legacy boot roms the system doesn't boot anymore. So the issue still persists, the screen still has the line effect, the only way I can temporarily resolve the issue is when I close the lid for 3-5 seconds and reopening it then the lines go away until next Reboot when I then need to repeat the same process with the lid. Thank you

Hi Jake, got the usb to boot cheers for the advice however another issue has occurred, upon booting and loading the installer I'm greeted my a page with lines running through. I've attached an image of what I'm seeing.

Apologies Jake, I attached it however it mustn't have uploaded. I've accidentally wiped the drive so I'm doing to remake the drive a bit later today and I'll update this post with the EFI Folder once I've recreated it

Here is the EFI folder you requested Jake. Thank you again for your assistance.

Hi Jake, Here is the output as requested. https://imgur.com/a/oJHRp I'm new to this so if there are any rookie mistakes apology in advance Thanks,

Thanks guys, it gets a bit further now however it now hangs at: iotimesyncclockmanager::interfacematched registered service Then I get a white circle with a line through it. Thank you for any assistance.

Hey Guys, Just looking for a bit of advice on creating a Installation USB capable of booting and installing High Sierra, all my attempts so far have been stalled by an "Attempting system restart... MACH Reboot" and it just sits there and hangs. Any info/help/guidance would be greatly appreciated. Cheers Error https://imgur.com/gallery/BNP8c
