How to Create a macOS Catalina Public Beta Installation USB

[P1LGRIM]

hey all, would you guys throw a bone out to someone who isn't too computer savvy?

I've created my installation media as per the document above... but when I try to select my bootable usb on the pc I am trying to install Catalina to.. I am met with a "missing operating system" message and unable to continue.

The only deviation from the guide that I am referencing at the top of this post is the fact that I am unable to select the partition tab, and then select GUID partition table. I followed everything else exactly as stated in the guide.

As I prefaced, I am not too computer savvy and I've been through all the Catalina forum pages to see if this message has surfaced elsewhere but I am not finding it anywhere.

Waste of time with a GTX 1070, there are no Catalina drivers for it - No Mojave drivers either.
Remove the graphics card and use the processor's integrated graphics or install High Sierra.

I sincerely appreciate the expeditious reply and extra help regarding graphics cards, but I'm still looking to see how to address the missing operating system issue when booting from USB.

@tuncerd : Have you found a solution to this problem?

I'm stuck at a very similar point (see attachment). I used the guide on page 1 and used the provided config and my mojave config.

You should try it with SSDT-EC.aml in /EFI/CLOVER/ACPI/patched.
