An errorlevel check is IMO mandatory after a cd command. Otherwise 
another bash in the PATH might be started if the directory does not exist.
Hmm... therefore it is also better to change the last line to:

   .\bash --login -i

The directory change is intentionally done with two cd commands to avoid 
possible problems with cmd variants (on Win10 "%~dp0" expands to a path 
with trailing backslash).
