I would imagine that you have the following in config.php:

// Set to true if you want pretty permalinks.

$bb->mod_rewrite = true;

Maybe change that to the following until you get the install up and running:

// Set to true if you want pretty permalinks.

$bb->mod_rewrite = false;

After that, head over to the documentation => Custimization = > Permalinks of the navbar at the top.
