Programming using a Raspberry Pi

dd is a common Unix program whose primary purpose is the copying and conversion of raw data

Usage: 

dd [Options]

Copy an image file to a hard drive or SD Card
dd if=/image.img of=/dev/hda bs=1000M

Now the hard bit is making sure that these names are correct otherwise you might loose your C drive. the bs option block size speeds up the process.
