Can I move Windows 7 to a larger partition with 'dd' instead of WinClone? I have a Modbook Pro with both Win 7 and OS X installed during build; no media provided.  I got fed up with all the irritations of the modbook and bought a regular Macbook Pro with a larger drive and OS X only.

If I create a bootcamp partition that is larger than the previous Windows, and copy the old partition via 'dd,' I will have a partition the same size as before with the remainder 'free space.'  Can I then stretch that partition with Disk Utility to get back the size I want?
While you could technically use dd to image a smaller partition onto a larger partition and it still show using the space of the smaller partition you'll not be able to resize the NTFS partition using Disk Utility.  Also the GPT and PMBR will not be synced and that will need to be resolved. Windows 7 will also need to be reactivated.

That said, using Winclone (at least Standard version) would be a much better option as it will handle what's necessary that Disk Utility can't, except for reactivating Windows, which is totally a Microsoft issue in resolution.
