Machine is MBP E-2011 500GB hybrid hard drive. Operating system is OS X 10.10.5 Yosemite.
I've encountered system issues that are difficult to resolve and have decided to reformat and reinstall OS X. I have prepared a bootable USB drive to install El Capitan 10.11.1 using DiskMaker X 5
When I use COMMAND+R at startup the Disk Utility shows "Disk2" "OS X Base System" underneath a divider below the title for my installed hard drive.
From what I have read this is a small recovery partition left from a previous install. All of my data is backed up elsewhere and I am installing from a bootable USB drive so I do not want this. I would like to install as if this was a blank, off-the-shelf replacement HDD.
How do I remove this "Disk2" "OS X Base System" before doing a complete drive erase and using my bootable USB?
Thanks

If it's under the divider, it's probably not on the installed drive. If you're booting to Internet recovery this is a temporary partition that resides in RAM, I believe, and not in the installed disk.
