I have Windows 7 Professional 64-bit installed on my desktop. Unfortunately for me and my wallet my hard drive is failing. I have purchased a 3TB hard drive as a replacement for my current 2TB drive. I would like to avoid as much hassle as possible in moving to this new drive so I would like to copy my current partition to the new drive using Gparted. The problem is that I suspect that my current partition is MBR, and I need GPT on my new drive since it is 3TB.

Can I simply copy the MBR partition onto the new disk and then convert it to GPT after the fact (can you even convert the type of a partition)? 

Or would I need to somehow copy the contents of the partition into a GPT partition on the new drive?

How do I go about making this transistion?

Also, are there any issues I should be wary of booting to a GPT partition? If it matters, my motherboard is 1 year old as of May, 2012.

Edit:
 My motherboard is 1 day old. My old one does not have UEFI compatibility, so I decided to make an upgrade to Intel today given that I would need a UEFI motherboard to use my new HDD.

How much can I use a dying hard drive (bad sectors according to Hitachi Drive Fitness Test)?  

I have assumed not at all, to be safe.

Edit 2:
 After two cloning attempts, nothing worked (direct cloning or cloning to an image). I just installed Windows fresh and then and copied everything I could. Honestly, after several days of stress with the cloning software, I would recommend this to anyone who has this problem in the future.
