This error indicates that your iPXE [[:scripting|script]] has attempted to ''[[:cmd:goto]]'' a non-existent label.

Things to try:

  * Check the script line that defines the label, such as<code>    :my_label</code>

  * Check the script line that attempts to ''[[:cmd:goto]]'' the label, such as<code>    goto my_label</code>Note that the label name specified in the ''[[:cmd:goto]]'' command must **not** include the colon ('':'') sign:<code>    # This is wrong
    goto :my_label</code>

  * If you are using a dynamically-generated label, such as<code>    goto host_${hostname}</code> then you should consider using a fallback label in case the dynamically-generated label does not exist.  For example:<code>    goto host_${hostname} || goto unknown</code>
