cd-rom couldn't be mounted after install started

[cladiron]

I was trying to install server 13.10 32bit on an HP Proliant DL360 G3
The cd was in a usb external DVD/CD player. (LG Slim Portable DVD Writer)
After the install had started up and passed the keyboard language detection, the install halted with the following error message.
https://drive.google.com/file/d/0B4Q90nHgQ35uZkxqci1ENy1RUXc/edit?usp=sharing

I tried a 2nd time to install, but had the exact issue.
I then removed the cd from the external player and inserted it into the internal cd player.
It then installed with no problems.

This is a testing server.
I have installed various versions of linux using the USB Drive, so that should rule out a BIO's issue.
