Cloning a Mac / Bootcamp disk to a larger drive
OWC and others recommend that you do a fresh installation when moving a Mac with Windows BootCamp to a larger drive. That is probably a good idea. Sometimes you just decide to do things the hard way. This is what I did for my Macbook Air when I bought a larger SSD. It had OS/X on the first partition and Windows 7 on the second partition. Backup your data. Create a Clozilla bootable thumb drive. Get an OWC drive with external case. Plug in the new drive in the external case. Boot Clonezilla from the thumb drive. Clone the internal disk to the new, larger, external disk. Make an exact copy of the disk using Clonezilla. This exact copy will not make use of the full drive. Power off the machine Remove the old disk. Install the new disk inside your machine. Boot into the mac OS on the disk you just installed. Move GPT bookkeeping data to the actual end of the disk. Download and use gdisk to copy the MBR/GPT info to the end of the new drive.
