How to get a backup a win8 from a SSd to ADHD or vice versa

Solution
The usual method to copy everything, (including Windows, the boot sector and the boot manager) from one drive to another is to use cloning software. Two free ones below (more if you search):

Clonezilla: http://clonezilla.org/

Macrium Reflect: http://www.macrium.com/reflectfree.aspx

After the cloning has been done, remove the HDD, then put the SSD where the HDD used to be.
