Emacs will automatically load site-lisp/site-start.el before your
.emacs, so you can change user-init-file there.

You could try leaving the drive letter off, so it defaults to the
current drive. If that doesn't work, then
(substring command-line-default-directory 0 2) or
(substring (car command-line-args) 0 2) should give you the drive
Emacs is running from.

M-x load-file
