Because of problems with third-party boot managers during PC World's 2008 Dream PC project, I wasn't expecting a whole lot from BootIt NG--I got more than I bargained for. Not only is it a very solid boot manager with a ton of setup and configuration options, it's a full-fledged partition manager. You can create, format, delete, resize, move (slide in BootIt NG-speak), copy, and much to my surprise--create and restore images of them.
Alas, as capable as BootIt NG is, it's that hard for a non-techie to use. There's none of the hand-holding V- com's System Commander and Acronis's OS Selector attempt to provide (not always successfully). It takes quite a bit of effort to create a dual XP/Ubuntu system, let alone the 98/Vista/XP/Ubuntu setup I finally managed. By the way, if your needs are simply a dual-boot XP/Ubuntu or XP/Vista system, stick with Ubuntu's (or other Linux) or Vista's dual-boot managers.
BootIt NG is arguably the best, most versatile boot manager out there. If you understand the technology and the process, it'll do the job nicely. If you don't, look elsewhere.
