ESXi 6.0U1 locking at 'Relocating modules and starting up the kernel...' how to resolve

Trying to install VSpere Hypervisor.

I am using a DELL Studio XPS with Intel i7 940 CPU with 18gb memory and 8 processors (desktop system).

I have created an ESXi boot dvd from the downloaded ISO.

When I boot from the DVD, the ESXi starts the boot process and then it hangs at:

Relocating modules and starting up the kernel...

I've read about this and found that when starting the boot process do a shift+0 and append the boot option ignoreHeadless=TRUE (Dell CS24 ESXi 5.5 Install Stuck "Relocating modules and starting up the kernel..." | RobWillis.info). I continue to get the error.

Should I not be installing on a dell desktop system, install on a server?

Regards
