I plan on installing Windows7 on a single partition on 80 Gig HD. Then I want to clone it onto another same model 80 Gig HD with Acronis True Image. Can anyone see where I would need a larger drive for the OS only? TIA srloren

The OS is fine, just barely. You just can't install programs where you want to sometimes and then you might be in need of more room. Since you have an image then you should be ok if you have to start over. Playing to the angels Les Paul (1915-2009)

srloren, Windows 7 system requirements If you want to run Windows 7 on your PC, here's what it takes: •1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor •1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit) •16 GB available hard disk space (32-bit) or 20 GB (64-bit) •DirectX 9 graphics device with WDDM 1.0 or higher driver http://windows.microsoft.com/system...
