I will be installing windows 7 HP 64 on a completely new computer with a single bare drive 640gb. I am confused by the partitioning aspect of this. Am I supposed to allocate a specific amount of the hdd to windows or just chooses the whole 640gbs? My old HP computer has a single drive with a separate section for recovery on it. Do I need to do the same thing? This is my first build I need all the info I can get. Thanks for any help with this. I tried search but cannot find any concrete information.
