bootcher :
As far as I know the F series pavilions come only with 1 slot for harddrive/ssd, so you can not add a 2nd drive. So you can replace the harddrive by a SSD. If you want you can get an USB kit for your 'old' harddrive and still be able to use it. Instead of only a SSD you might consider a hybrid SSD: http://pcpartpicker.com/parts/internal-hard-drive/#t=1&sort=a10&f=3.
I will either try to get a hybrid or just use a 250gb SSD. Like I said I just would like to be able to boot and sign on within seconds as it makes it much easier for school since I'm turning my laptop on/off every class. And I don't need a ton of space since I already have a gaming PC. I just use it to access online textbooks, and to write code.
EDIT
I see most hybrid drive only contain approx. 8gb of SSD cache. This doesn't seem like much for an OS, I think I'd be better off with a 250gb SSD.
