Bill Gates can be really confusing ! I have Windows Vista, but it says you need a minimum of 256 MB of RAM. So I decided to give up and get more RAM. I checked the Installer notes it comes with an it says "In this release of "Longhorn" versions of Windows, you will be unable to install mass storage drivers by using the Load driver option on computers with less than 256 MB of memory. To work around this problem, add the additional drivers to the Windows Preinstallation Environment (Windows PE) before running Setup. Refer to the Windows Automated Installation Kit for more details about adding drivers to Windows PE." It says you can "work around this problem" so I'm guessing you can install it. I don't understand how to install it now
