After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume.

Terminal shows the progress as the volume is erased. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal doesn't show any characters as you type. When prompted, type your administrator password. If the volume has a different name, replace MyVolume in the command with the name of your volume. Each command assumes that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. Type or paste one of the commands below into Terminal, then press Return to enter the command. Open Terminal, which is in the Utilities folder of your Applications folder. Plug in the USB flash drive or other volume that you're using for the bootable installer.
