I've been pulling out my hair trying to solve this, a new S2600CP Board, dual Xeon E5-2630s, is unable to boot to the IDA v5. I've tried several different types of media, including USB boot, and several copies of the disc, however I always receive a "Unable to access boot device" error.
So far I've replaced RAM (Currently using 16GB of Crucial workstation RAM), both processors (tried with a single processor as well), multiple boards (fully up-to-date firmware), every SATA configuration, and several different methods of booting to the IDA.
I'm at complete loss here.
If you're using a SATA optical drive, set it in AHCI mode. During boot, press F2 and go to "Boot Manager" to select boot device.
