I tried a gen 10 plus with intel g5420 but it doesn't boot from the USB prepared with Win32 Disk Imager as the following guide says.

i tried 918+ and 3615xs loaders.
Have you some advice to prepare the usb stick?
Anyone tested the internal usb for boot?
Some bios setting are necessary? (I set ahci and usb are enabled)
It boot up correctly if i use with external USB DVD with linux ISO.
