Becoming skilled in B.I. requires skills in installing images and virtual machines. To install a new O.S. from a USB flash drive in Windows mount the ISO image using your favourite virtual drive software. Now open a CMD prompt (run as Administrator or you will get Access Denied) then issue the following xcopy command :
xcopy D:\*.* E: /s/e/f
…where D: is the location of your mounted ISO image and E: is the location of your USB flash drive.
If you are having troubles there is a fabulous piece of freeware (at the time of writing) called ISO to USB http://www.softsea.com/download/ISO-to-USB.html that takes the hassle out of the process. Simply install and run the utility, then browse to your ISO file, nominated the USB drive to format, and away you go.
As long as your BIOS is set to boot from USB – Happy days.
