Missing Operating system after install

Burned the iso: FreePBX-2.210.62-6-i386-Full-1363357527.iso

Running this on a one drive system, I choose FreePBX 2.210.62 with Asterisk 1.8 Full Install – No RAID.

The package appears to install and reboots… but it boots into the CD menu again. I remove the CD and reboot and it says Missing Operating System.

Any ideas?

First off, check your iso against the published md5sum.
