A default bootable media can be select in the BIOS and by default the raid controller card (PERC) will be selected first. Files available in a bootable device (RAID, USB key, DVD, ISO file) contain instructions to start the operating system. When these files cannot be found, the error "No Boot Device Available" is displayed.
