From the age of the BIOS (2010) and the date of RHEL-7 coming out 2014.. you are at the cusp of upstream hardware support. The problems you are describing could be anything ranging from BIOS/Mobo incompatibility to a whole host of things which would take a while to debug. I would do the following: 1. See if CentOS-6 runs on the hardware. If an ISO fails to boot either via USB or DVD in a similar way then it may be a hardware issue. 2. Download an older version of CentOS-7 from vault.centos.org and see if that will install. 3. Start looking at the hammer boot options which various motherboards need. These can range from acpi=off noapic or a slew of others. [Google for ones which might match your hardware.] There are 10's of thousands of motherboards manufactured and trying to enumerate which ones aren't usable is not something any volunteer project can do. -- Stephen J Smoogen.
