Bootcamp Assistant on Mountain Lion

Hey apple pros.

Question. After creating the windows partition, my MacBook restarted but it's stuck at the white apple screen. I'm using an 8gb USB stick to install windows 7.

However, I read that mountain lion does not support installation of windows via bootcamp if there is no SuperDrive present. I replaced my SuperDrive with an ssd.

Would just like to confirm if this is true?
