Well, I was able to find a work around for this issue. The problem is just with host registration (both quick and full). If I add the hosts manually and then add a task for each host to download the image it boots and works as it should.

I am definitely giving it enough time. I left it for 45 minutes and it was still at the same percent. After playing around with it for 2 days I found that if I reboot the fog server then boot the machine right when the server hits the login prompt it will work about 25% of the time, and it immediately passes this point without even showing a percent on the screen when it works. Is it possible that there is a service that starts that prevents it from working and I was able to get it to work by booting before that service started?

I have also tried different kernels, switched from Ubuntu to CentOS, and even tried a different server hardware… these OptiPlex 320s just do not like to be imaged. All other workstations I have imaged work fine.

We are getting closer. The original error went away and now i am stuck at bzimage. The percent is different for different undionly files, but they all hang there. The ipxe files just reboot the machine. Any additional help appreciated.

Did anyone find a solution for this yet? I am struggling with some Dell OptiPlex 320s and have tried all of the boot images. I still get the same error… input/output error ([url]http://ipxe.org/1d8c2139[/url]). Thanks in advance.
