@Wayne-Workman I have checked the md5 checksum of the iso file and it matches the one on the website. Do you still think I need to re download?

@Sebastian-Roth One again spot on Sebastian
I can now boot from the iso but this is not the end of it yet! When it goes through the boot process I get this error :

This happens if I choose the Linux rescue environment . If I choose mini windows xp, everything works fine!
Any suggestion for this one ?
I also have a general question: How do I know how to treat a iso file to be able to boot from it on FOG? There is a wiki page for some (which I think is not updated in a while).
Is there any instructions to follow or it changes every now and then?

@Sebastian-Roth good point. I just tested it. I can access the iso file from the FOG server machine : 127.0.0.1/iso/hiren/hirens.iso
but from other machines if I do : 192.168.18.28/iso/hiren/hirens.iso I get to the FOG
server management page. Seems like no matter what I type after the ip address it forwards me to the FOG login page.
I have checked the permissions for the iso folder and changed it to “-R 777” (I’m not sure if this is a good practice!) but still the same.

@george1421 Finally got it working for the Ubuntu! using the instruction you provided!

Regarding Hiren I still have problem. I have changed permissions as @Tom-Elliott suggested but for the /var/www/html/iso/hiren/ (hirens.iso is in this folder)
Now it gets stuck with this message:

Loading  boot sector... booting ...

Btw for the reference and in case someone needs it later I will post what I did here in another post.

@Tom-Elliott Thanks Tom. Did that but nothing changed!

Thanks george for the quick response.
So I have done what you mentioned:

1. I did move the hiren iso file to /var/www/html/iso/ and changed entry in the MENU to this:

:hiren
initrd http://${fog-ip}/iso/hirens.iso
chain memdisk iso raw ||
goto MENU

Now when I choose hiren I get this message:
MEMDISK: bootstrap too large to load.

It was booting before at least to windows not it does not. DO I need to change something ins the “chain memdisk iso raw ||” line?

2. For the Ubutu entry:

A. I changed the protocol to tftp:

:ubuntu
kernel tftp://${fog-ip}/tftpboot/ubuntu16/vmlinuz.efi
initrd tftp://${fog-ip}/tftpboot/ubuntu16/initrd.lz
imgargs root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:${fog-ip}:/images/mounts/ubuntu16  locale=en_US.UTF-8 keyboard-configuration/layoutcode=us mirror/country=US
boot || goto failed
goto start

The result was that I get this error message:

vmlinuz.efi is in /tftpboot/ubuntu16/

B. I tried to use the http instead so I created: /var/www/html/os/ubuntu16 and extracted the ubuntu iso here.(after reading many posts I’m still not sure that I must use the iso file or extract it into this folder!) so here is the folder content:

Andhere is the MENU entry for it :

:ubuntu
kernel http://${fog-ip}/os/ubuntu16/vmlinuz.efi
initrd http://${fog-ip}/os/ubuntu16/initrd.lz
imgargs root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:${fog-ip}:/images/mounts/ubuntu16  locale=en_US.UTF-8 keyboard-configuration/layoutcode=us mirror/country=US
boot || goto failed
goto start

I still get the blank page when I choose to boot from the ubuntu entry.

What about the imgargs line? do I need to change the nfsroot path in this line? and what should it be in this case?

Description

I want to boot from a Ubuntu 16.04 live iso but I have failed so far.
I have followed the instructions here: link text and here : link text but still I can not get Ubuntu to boot.

When I choose Ubuntu in the advanced menu: I get ok for loading “vmlinuz” and “initrd” then I get a blank screen with cursor blinking and nothing happens afterwards.

Here is the content of my advanced menu:

:MENU
menu
item --gap -- ---------------- iPXE boot menu ----------------
item ubuntu Ubuntu 16.04 x64
item hiren Hiren Boot CD
item shell ipxe shell
item return return to previous menu
choose --default return --timeout 5000 target && goto ${target}
:ubuntu
kernel http://${fog-ip}/tftpboot/ubuntu16/vmlinuz.efi
initrd http://${fog-ip}/tftpboot/ubuntu16/initrd.lz
imgargs root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:${fog-ip}:/images/mounts/ubuntu16 locale=en_US.UTF-8 keyboard-configuration/layoutcode=us mirror/country=USip}:/images/mounts/ubuntu16
boot || goto failed
goto start
:hiren
initrd http://${fog-ip}/fog/service/ipxe/hiren/hir.iso
chain memdisk iso raw ||
goto MENU
:shell
initrd http://${fog-ip}/${fog-webroot}/iso/ubnt.iso
chain memdisk iso ||
goto MENU
:return
chain http://${fog-ip}/${fog-webroot}/service/ipxe/boot.php?mac=${net0/mac} ||
prompt
goto MENU
autoboot

The menu item that I’m working on is “ubuntu” I have been trying other methods at the same time so there are other menu items as well.
In the ubuntu Menu item I tried the instructions from Fitzzz (Booting Ubuntu 16.04 ISO from FOG) but as APPEND command was not recognized I had to do changes in commands a bit.

So far I have only managed to boot Hiren and only in mini windows mode. the linux environment does not boot in Hiren.
I’m new to this and most probably naive but I assume it should not be super hard to have couple of live images ready to boot from FOG using PXE.
I have read the wiki and many posts in 24 hours but seems to be nothing is organized and different instructions say different things.
Thanks for your input in advance

@Sebastian-Roth Thanks Sebastian. You are right! I was not sure if I should post here or create a new topic. I felt bad just to create another post while this was related to the same (kindda) issue.
I have followed the instructions in the link but still have problems. I will create a new topic and post dubug info there

• list item
  FOG version : 1.4.4
  OS: Ubuntu 16.04.2 X64

I want to run a ubuntu 16.04 live iso using pxe on my client. I have read all the guides in this topic.
I only managed to make the Hiren boot to work(only the mini windows works and not the linux enviroment). I have followed instruction from Biet Jeremie to fill in the advanced setting box for Ubuntu iso file. When I choose Ubuntu from the advance menu it loads the Ubuntu menu and when I choose:
“try ubuntu without installation” it says it can not find the medium congaing the live file system.
I have two problem:

1. I don’t know if the instruction provided has changed from the date this was discussed?
2. I’m not sure if I just need to copy the iso file from Ubuntu or I need to extract it in some folder?

Has anyone got this to work?
