RHEV-H 6.2 won't boot after install

My Host is an IBM System X 3650 M3 the Hypervisor I have installed is the rhevh-6.2-20120320.iso

Instllation goes ok and the Hypervisor seems to be installed. Then when ask to remove the bootable media and rebbot the computer the host reboots and an error message comes very fast saying "No operating system found" 

I found a similar case here https://access.redhat.com/support/cases/00629027 , the only difference is that the case is mentioning a System X 3550 and my System is the 3650 I can't find the bios option mentioned in the case.

Is there any workaround to this problem with my system?

Thank you
