If you’re like me an have an older laptop that doesnt have a cd/floppy drive or the BIOS doesn’t support booting from a USB device (thumbdrive,etc), you can boot your computer from USB or CDROM using PLoP.
The PLoP Boot Manager is a small program to boot different operating systems. You can boot the operating systems from harddisk, floppy, CD/DVD or from USB. You can start the boot manager from floppy, CD, network and there are many more ways to start the boot manager. You can install the boot manager on your harddisk. There is no extra partition required for the boot manager.
The install is super simple, you just copy 2 files to the root of your cd drive ,run a command, add a PLoP entry to your boot.ini and you’re done. Now you can run all your favorite linux-on-a-stick like BackTrack3 or Barts without the need for vmware etc. More Info ::HERE::
