Hello I have an ssd with only 10 gb of space remaining with windows 7 on it, my college is selling windows 8 pro upgrade cheap and I want to get it I am wondering will I be able to install it on this SSD or will space be an issue? Can I just delete windows 7 and replace it by windows 8 during the installation? cause I read u need 20 gbs of free space, but im not sure.

the SSD is a 64 gb corsair force, however it shows 45 GB in my computer settings, another 10 GB is being used by windows 7, ive moved the page file and deleted the hibernation file leaving me with 12 GB free space, most of my (if not all) programs games and videos are on my 2TB WD green HDD ... I literally dont know how much more I can clean of this SSD. Will it be enough to get windows 8? I dont want to keep windows 7, can I clean install with the windows 8 pro upgrade.
