Hi all,

I have ClearOS 5.2 and I want to provide the option for workstations to PXE boot into a Ubuntu LiveCD.

This is what I have done so far:
* created a flexshare called netboot where I have placed the latest Ubuntu Desktop ISO image
* Installed nfs-utils and palced the following line in the /etc/exports file:
/var/flexshare/shares/netboot *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)
* Restarted NFS
* I have correctly setup DHCP
* Downloaded the Netboot file for Ubuntu and extracted it to the netboot share.
* A workstation can successfully PXE boot and get to the menu and I can run the Install option in the menu

The problem is that the pxelinux menu does not have a Menu Item for starting the LiveCD and I can't figure out now how best to do this.

The 2 options I see are as follows:
1) Get the menu to "mount" the ISO and start Ubuntu
2) I extract the contents of the ISO to the netboot share and set the menu to start Ubuntu.

Any thoughts on what the menu items should look like?

This is what the pxelinux menu files currently look like:
