The iso I’m trying to load is a customized lubuntu image which boots and works just fine as a live image on some local host computer as well as in a virtual box. I have mounted the .iso file in the [url]http://${fog-ip}/fog/lublive/trusty[/url] directory using the command:
[INDENT=1]mount -o loop lublive1.iso trusty/[/INDENT]

Configuration 1:

:lublive1
initrd [url]http://${fog-ip}/fog/lublive/lublive1.iso[/url]
chain memdisk iso raw ||
goto MENU

The iso image appears to download, the lubuntu splash screen appears with the loading bar, then it shows the following:

[INDENT=1]command line: iso raw[/INDENT]
[INDENT=1]MEMDISK: Image seems to have fractional end cylinder[/INDENT]
[INDENT=1]MEMDISK: Image appears to be truncated[/INDENT]
[INDENT=1]Disk is hd96, 149248 K, C/H/S = 65535/255/15 (El Torito/El Torito), EDD on, rw[/INDENT]

Configuration 2:

:lublive2
kernel [url]http://${fog-ip}/fog/lublive/trusty/casper/vmlinuz[/url] boot=casper netboot=nfs
nfsroot=[url]http://${fog-ip}/fog/lublive/trusty[/url]
initrd [url]http://${fog-ip}/fog/lublive/trusty/casper/initrd.lz[/url]
boot || goto MENU
autoboot

The pxe boot fails immediately and boots from the harddrive

Configuration 3:

:lublive3
imgfetch [url]http://${fog-ip}/fog/lublive/lublive1.iso[/url]
boot memdisk iso raw ||
goto MENU

Once again the iso image loads, the splash screen appears, but the result/error is the same as Configuration 1.

Configuration 4:

:lublive4
kernel [url]http://${fog-ip}/fog/lublive/trusty/casper/vmlinuz[/url]
initrd [url]http://${fog-ip}/fog/lublive/trusty/casper/initrd.lz[/url]
imgargs vmlinuz boot=live config console=ttyS0 fetch=[url]http://${fog-ip}/fog/lublive/trusty/casper/filesystem.squashfs[/url]
boot

it appears to load vmlinuz and initrd but then the screen becomes blank and is unresponsive, I let it sit for a while in case it was loading the image and just taking a while but nothing happened.

I also tried booting the unaltered standard lubuntu image and although it didn’t show the initial Memdisk errors as before, it still loaded a BusyBox shell and said “Unable ot find a medium containing a live file system”

Any help or insight would be much appreciated.
