Hiren’s BootCD (also known as HBCD) is a bootable software 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. HBCD can be considered a valuable tool for use in troubleshooting and recovery of computers.
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). Most of the tools are also available when the operating system is already started.
