I am seeking a program that can encrypt a whole hard drive when Ubuntu 12.04/ Windows 7 installed on the same drive (different partitions) using a grub loader. I cannot seem to get TrueCrypt to accept this, and I am curious if there is a work around (lol) or another open source encryption program anyone may suggest?

I'd recommend a self-encrypting hard drive (SED). Not perfect, but they do work, and they don't slow down your system, except for bootup (assuming you are putting the decryption key in the pre-OS-boot sequence). These are becoming more mainstream in business/enterprise and widely available (Dell sells them as part of a system package, now, e.g.). Here's a vendor page with some info : Western Ditgal/HGST Self-Encrypting Drives.

Truecrypt and grub don't get along. You can use bitlocker and chainload grub from boot.ini. Then use luks on the linux side.

There are several commercial solutions from e.g. Symantec, but they are not cheap. The simplest solution for that is to use Bitlocker.
