Thanks, that’s very helpful. I’ll do some debugging and see what I can find.

After fiddling around with several different arrangements I finally found that the following filesystem layout works:

.
└── EFI
    └── BOOT
        └── BOOTX64.EFI

with nothing else on the drive, and where all names seem to be case-sensitive (I couldn’t get it to work with bootx64.efi or BOOTX64.efi).

The documentation at the 2nd link above says that after booting I should be prompted for the IP address of the FOG server. That doesn’t happen for me. Instead, ipxe tries to connect to the server from which I copied ipxe.efi (which is on the other side of a firewall) and fails.

From subsequent ipxe command line I can use “chain”, etc., commands to talk to the server on a different, non-firewall-blocked address.

Over the years, several people have posted instructions for creating bootable USB fog image installation/capture disks. For example:

and

https://wiki.fogproject.org/wiki/index.php?title=USB_Bootable_Media

Unfortunately, none of these methods seem to work now, at least for the current Dell Optiplex computer I’m testing with.

Does anybody out there have updated instructions that are known to work with recent computers?
