Thanks for the screenshots, they explain what is happening. It would
have been possible to identify the issue earlier given the exact error
message, "it says no unique boot image is found" is not the same as
"No (unique) loaded image".
The problem is that a previous boot attempt has failed and left
boot.php loaded. When you load vmlinuz from the gPXE shell there are
now two images: boot.php and vmlinuz which could be executed. gPXE
does not know which one you want to boot.
Either hit Ctrl+B before the initial DHCP and boot attempt, or use
"imgfree boot.php" to get rid of boot.php before issuing the boot
command.
Hope this helps,
Stefan
