Install: Partition showing up as /CD-ROM

I have a 2011 Mac Pro that I have used Linux on it before and tried several distros on it.. 

Backslash looks amazing and I loved the Pantheon desktop in Elementary OS. Just had some major glitches with it like suspending would have to reboot entirely...

Anyway to my issue.

When using a disto on my Mac I always make an MSDOS Partition. Generally 200GB+ as I like linux better than MacOS.

This is what I get looking at my partitions when trying to install Backslash

SDA3/ is my MSDOS partition

As you can see it shows the Mount Point as /cdrom 

I have never seen this before with any installs of Linux.

I cannot select the partition or anything else like that

Any help would be highly appreciated.
