what's a dual boot?

Basically, you install two (although there isn't technically anything stopping you from putting more than one in) Operating Systems, and have a method of picking the one you want to use now each time you boot, so that you can (for example) run programs that are exclusive to the Windows environment while still using all those nifties you like in Linux (just not at the same time). Alternately, it is possible you have multiple Users of the same machine who like different OS's, and a dual boot can accomadate that. There are likely other possible reasons for it.
