   Instead of   
      
      cd /d %temp% & start "" %~n0.bat   
      
   use:   
      
      cd /d %temp% & start "" cmd /c %~n0.bat   
      
   or:   
      
      cd /d %temp% & %~n0.bat   
      
      
   In the second case you have to avoid the () in  the   
   if statement:   
      
   if /i "%cd%"=="%temp%" goto :temp   
      REM we are running from original location %cd%   
      copy %~n0.bat %temp%   
      REM copy RemoveDrive.exe %temp%   
      cd /d %temp% & %~n0.bat   
   ::  ECHO Finishing the original BATch file...   
   ::  PING -n 21 127.0.0.1 > nul   
   ::  endlocal & exit /b 0   
      
   :temp
