Poster heres info on GPT drives from MS:
Using GPT Drives Note: Installing a Windows x64 Edition operating system on a GPT disk is not supported. Attempting to do so yields an error. Although Setup allows you to choose a GPT disk partition on the partition selection screen during Text Mode Setup, doing so displays an error message. To assist users in avoiding this error, the partition selection screen clearly indicates whether the partition is configured as an MBR drive or a GPT drive.
I think its basically saying you cant use a GPT drive or format it to NTFS to use Windows, so looks like a new hard drive.
