One particular problem with Windows is that, if you want to make changes to
your system, once you've installed software and configured external hard drives,
Windows makes like more difficult than you'd expect.
If you want to partition your hard drive within Windows, only a small number
of partitioning tools enable you to do this and only when the hard drive is not
in use.
BootIt NG is a tool that enables you to create a bootable CD that you can use
to boot in to a custom operating system (ie outside of Windows) and make changes
to your system without affecting your Windows installation or work.
Better still, it works within every edition of Windows and will even enable
you to extend or delete partitions created outside of Windows, such as a Linux
partition.
If you want to install multiple operating systems on one computer (such as
Windows and Linux), you can use BootIt NG to setup your system so that it can
use one partition to multi-boot more than one operating system.
If you make mistakes, such as accidentally deleting a partition, BootIt will
enable you to go back and undelete the partition.
