Hey guys, I have a Alienware 17 r2 2015. I opted out of getting the included SDD, but now I'm kind of regretting it as the HDD is SO SLOW! I have been looking online at getting a single SDD M2 drive. My question is how do I migrate info and instal the new OS without a disc. As we all know, there is no optical drive for the new laptops. So how do I install windows 7 onto the new SDD? Second question is how do I set up the HDD as a backup? Do I need to reformat the HDD before installing the new SDD? I'm confused as hell. So if anyone can help me with this, that would be great! Thanks all!
