I have the same problem with FreePBX-64bit-10.13.66.iso when I try to install it through a virtual CD-ROM, configured in Supermicro IPMI remote console to use the ISO image on a Windows share. I tried both FreePBX 10.13.66 with Asterisk 11 “Full Install” and “Full Install – Advanced”. There was such bug in RedHat back in 2010 (https://partner-bugzilla.redhat.com/show_bug.cgi?id=613576) with accessing CD-ROMs, but it was fixed then. Probably SchmoozeOS has the same problem?
