Hiren’s BootCD is an all in One Bootable CD containing a number of diagnostic programs such as partitioning agents, system performance benchmarks, disk cloning and imaging tools, data recovery tools, MBR tools, BIOS tools, and many others for fixing various computer problems. As it is bootable, the operating system of the computer need not be available for the tools to be usable. All that is required is that the computer is able to run Microsoft Windows and Linux (but it does not have to have either of these installed at the time of use). Some of the tools are also available when the operating system is already started.
Hiren’s BootCD is available as an ISO image zipped. The image file can be burned to a CD or onto a USB flash drive for use on computers that support booting from USB. Hiren’s BootCD is based on Knoppix (a bootable Linux operating system) and a collection of other freeware tools.
