I have an old Dell Dimension 4100 that I am going to put Windows 7 on just to see if I like it. It has a 19gb hard drive in it. Windows Upgrade Advisor says that I need 16gb of free space to install Windows 7. Am I going to have a problem installing Windows 7 on a hard drive that small? Right now there is only 9gb's of free space with XP Home installed.
Why does Windows 7 need 16gb of free space when the size of the file is only 2.35gb's?
