Hi there, I've already erased the Harddrive but can I also erase the OS X Base System (Disk 1)? Would like to restore to factory settings.

Look forward to your response!

your OS X base partition does not contain any user data, at least I don't think so

but if you still want to remove it I suggest making a bootable install media there is a guide here How to create a bootable installer for macOS - Apple Support then boot to the installer by restarting and holding the option key, select your install media and hit enter. Open disk utility and erase
