i've previously successfully installed and ran "NetBSD-9.0-amd64.iso" in VirtualBox v6.1, in GPT partitioned disk, in their default BIOS configuration (Not their UEFI). that seemed to work OK.
Now in my Linux installation in Bare Metal, i'm using 'dd' in this format:
dd if=<file> of=<device> bs=1M; sync
But both the "NetBSD-9.0-amd64-uefi-install.img.gz" file (after extraction), and the "NetBSD-9.0-amd64.iso" file is failing to Boot in Bare Metal.
As for the "NetBSD-9.0-amd64.iso" file, after dd-ing to my USB Drive, nothing shows up in my motherboard's UEFI menu. As if it can't recognize it at all.
And dd-ing the "NetBSD-9.0-amd64-uefi-install.img.gz" file (after extraction), my motherboard's UEFI menu can recognize it. When i choose it, then comes the official NetBSD menu.
Gives me the option to either boot NetBSD, or go back to boot prompt.
After selecting to boot NetBSD, a little loading occurs, and then it gets stuck. Nothing comes after.
So how do i successfully load the NetBSD installer and run it in my Bare Metal?
