Hi there MyKeyblader,

As far as I understand, you had a boot hard drive with Windows 7. Also, you had another drive(not installed on this computer) with Vista right?
If this is the case, you will be able to get your photos if you boot with Windows 7 and access your other drive(the one with Vista), which will be a secondary one.

Hope this will help,
