try following , keep informed it works:

$xml = [xml](get-content "<yourxmlfile>.xml")  [system.xml.xmlnamespacemanager]$nsmgr =$xml.nametable $nsmgr.addnamespace('urn', "urn:schemas-microsoft-com:unattend")  $tmp = $xml.selectsinglenode("//urn:disk[urn:diskid=1]", $nsmgr)  ($xml.selectsinglenode("//urn:diskconfiguration", $nsmgr)).removechild($tmp)  format-outerxml $xml

hope helps,
