There are a couple of ways.

Save the file with a sightly different name before editing it and use the
GRUB shell interactively at boot to choose your backup configuration
instead of your edited version, thus to boot as you are now.

Use a live CD to change your edit back to what it is now or delete
the newly edited file and rename your backup back to menu.lst.

But you won't likely make a mistake, it's easy to cut and paste the
Windows stanza to the correct location.
