So last night I was having a lot of problems installing a 64 bit version of Windows 7 home on my new Haswell Air. I attempted a 3rd install using bootcamp assistant and hit the enter button too many times that it jumped right to creating the default partition of 20 GB. I couldn't stop it, however it actually installed fine. After disabling hibernation and limiting the page file to min/max 1.5 gb, the total size used with most of the updates installed (except SP1) came to 18 gb. Since I only use bootcamp for playing Steam games off an external thumb drive, should I be worried about my initial partition size? If I started over again, would I have problems with my Windows activation considering this would be the third time using the same product key for only 1 computer? I appreciate your response in advance!
