What does your startup sequence look like? Assuming you're trying to install the OS from optical, you should have the optical in front of the HDD in the startup sequence, and you might have to hit a key right after POST in order to boot the system to the DVD.
That message you're seeing looks like it might be a log from the secure erase utility. That's a utility usually used to wipe media. I'm guessing this is displaying because your system is booting to a blank (but formatted) HDD that's been scrubbed already.
