This mini-HOWTO covers some ways on how to install both Linux and Windows NT on the same computer and how to boot either of them from within LILO menu. There is also another mini-HOWTO "Linux+NT-Loader" that covers how to boot either of them from within NT Loader menu. As I consider Windows 2000 to be Windows NT version 5.0 this mini-HOWTO also covers upgrading from NT 4.0 to 2000.
