I've never used emacs, and my Dos batch-writing skills are rusty, so
all I can offer is a conceptual solution. Presumably, your emacs
distribution contains a directory not found on any other drive (e.g.
<drive_letter>:\MyEmacsDir\). Any unique path will do. Simply have
the desk icon start a batch file that begins as follows:
dir C:\MyEmacsDir\
If error: directory not exist, continue : else set variable_1 to 'C'
and then goto Label_1:
dir D:\MyEmacsDir\
If error: directory not exist, continue : else set variable_1 to 'D'
and then goto Label_1:
dir E:\MyEmacsDir\
If error: directory not exist, continue : else set variable_1 to 'E'
and then goto Label_1:
...
Label_1:
set <Emacs_Home> to %variable_1%<desired_path>
execute %variable_1%:\<desired path_name + executable file_name>
