A bootkit is a rootkit that is able to load from a boot-sectors (master boot record, CD , PXE , floppies etc) and persist in memory all the way through the transition to protected mode and the startup of the OS. It's a very interesting type of rootkit. All rootkits install when the OS is running because they use the OS' features to load (and also they use the Administrator privileges to install), but bootkits are different, they use the boot media to attack the OS , and thus survive. Vbootkit is a bootkit specific for Windows Vista.
