Map the iso in and choose the recover mode. See if it can find your OS disk. Sounds like it might be a gpt partition issue? How big is the boot disk? Is the bios set to legacy of uefi mode? Is secure boot turned off?
Regarding Ubuntu, we always stick with the LTS versions. Everything else should be considered beta. Tried 14.04 LTS? 16.04 is not far off which is the next LTS.
Also you are using the alt/server Ubuntu iso's?

No difference... still does not boot. FWIW, I see that the boot drive is being accessed after the BIOS completes, but nothing happens...

Hi,
Maybe it's a pxe config file problem, please, to check this, try to unplug the ethernet cable and reboot.

Hi all,
Have been trying to install Ubuntu 15.04 via Cobbler (both using kickstart and preseed) - the install looks normal, completes, but then when the machine reboots, it hangs after the BIOS screens where it would normally display the GRUB menu... I have tried this process on two different Dell PowerEdge machines (an 1850 and a 1950) but the same thing happens every time. I can successfully install on either of these machines if I use the regular Ubuntu 15.04 CD to install. Anyone seeing this, or have any suggestions on how I might troubleshoot? I have booted the Cobbler-installed machines with an Ubuntu rescue CD, and did the "reinstall GRUB" option, but they still won't boot thereafter...
Thanks,
Will
