3. You would need to use part magic or something similar to shrink the current os partition to under 120gb. Then, once you have that done use clonezilla to copy the system reserved partition and the os partition over to the ssd. Then go into the bios and tell it to boot from ssd.
As Ryan. Mentioned though, Windows doesn't play nice when it comes to changing hardware on an existing windows install. Might be easier just to start from scratch.
