linux - Copy existing Ubuntu drive to partition on new hard drive

I have a new laptop with two partitions, one is currently loaded with Windows 7, the other is blank.

I'm pretty familiar with using dd to backup/copy drives, but I'm wondering how I will deal with the boot loader on the new drive, being that there is an existing Windows install. After I copy the Ubuntu disk into the new partition (which is larger than the Ubuntu disk), what would I need to do to set up the boot loader with the existing install of Windows (which the current Ubuntu loader will not know about)?
