Best FREE OS transfer software?

[Holahoops]

So I got a SSD for christmas and I already have a HHD with my OS and all my stuff on it and I was wondering if there is some good, FREE software that I can use to transfer just my OS onto my SSD.

 

Thanks for any help

I think Samsung has some software that does that. Somebody else must know the name.

So thank you guys for helping but I looked at some tutorial videos and I don't want to accidentally wipe my drive so I guess ill just wait the extra 30 seconds to boot
