Getting Error about "Ntfs.sys" When Installing Windows 7

I've been trying to install Windows 7 Ultimate via Bootcamp and I keep hitting up against an error when I try to boot into the Windows installer. After loading system files and briefly showing the Windows loading screen, it gives an error about missing/corrupt drivers, and references "Ntfs.sys". I've attached an image of the full error.

I can't seem to find any solution, so I'm hoping someone on here will have an idea.
