How to erase  disk image??

I'd like to know how can I delete (erase) Apple disk image Media.

Normally when I open Disk utility I'm not able to see this. Only when I'm in Disk utility in Recovery Mode (⌘+R).

I'm not sure what that means and how can I erase it - that's why I'm asking 🙂

Here's how it looks:

This disk image is listed under "Disk images" section and it is external type of disk. It has also 2,14 GB in total.

How can I completely remove it?

I also tried typing

diskutil list

into Terminal when I was normally logged in. It wrote me:

I appreciate any help.

MacBook Pro (Retina, 13-inch, Mid 2014), macOS Sierra (10.12.3), null

I'm curious about this as well. Does the "Apple disk image Media / OS X Base System" contain any personally identifiable information? I'm preparing an early '09 24" iMac to go to another user. I've followed the steps in this kdb article https://support.apple.com/en-us/HT201065 as best as possible and want to make sure the drive retains no account information. I am not able to select and erase the HW-named drive ("WDC WD1001...") after command+option+r reboot (see attached,) but did successfully securely erase "Macintosh HD" volume. Is there anything left on the drive or in the Disk Image the next user could recover?
