How do I copy my bootcamp dmg file back to my harddrive

To begin, I had installed windows 8 with bootcamp, but after about a year I realized I needed more space. I tried to shrink my mac partition and expand my bootcamp partition, but it wouldn't allow me to increase the bootcamp partition. So I planed to make a img file of the bootcamp partition, then delete the bootcamp partition, then make a bigger partition and put the image file back on. I have already backed up and deleted the bootcamp partion. So my question is how do I make a new NTFS partition and burn the image file onto it. BTW the image file is a .dmg file. I would like to do this with Disk Utility, but im up to trying third party software.

Mac mini, OS X Mavericks (10.9.5)

There is no clean way to restore a .dmg of Windows back to disk. You can restore it back to the original Mac and try tools similar to Winclone or Camptune for backup and restore. If you restore it to a larger partition, a hybrid MBR can be created which let you mount the volume, but Windows may require Startup Repair.

A NTFS partition is not sufficient by itself to help you run Windows. Boot Manager and Boot sectors will still cause issue. What is the year of your Mini?

Disk Utility is not 3rd party, it is an Apple product, part of OS X.

I know that. I merely stated that if I cant use Disk Utility, then I would look for other alternatives.

You have already deleted Windows. I suggest you restore it back exactly as it is and verify that Windows is working, and then use Winclone or CampTune.

Can you restore the DMG to the same sized partition first and verify its viability? Restoring a DMG is very different from restoring a Windows System Image. Instead of a DU DMG, Windows should have been backed up using Windows utilities, but since it is already done, there is no way of going back.
