Hi... I work for a solutions company, and I'm trying to make my life, as an engineer, a bit easier. I have made a bootable ISO image of Windows XP, with a whole bunch of customizations done, and some custom software, our company makes, installed. Its just at the moment, everytime a change needs to be made, I have to make the change, recreate the image, burn it to disc, then load it onto a new machine to be sent to a client, all done nicely for them, to plug and play. This is instead of building Xp PC's everyday from scratch. What I'm looking for is a way to put the ISO image on a bootable USB key, so that I can make changes easily, without having to make unneccessary copies over and over again. Pull out a new PC, plug in the USB key, turn on the PC, let it boot off the USB key and a while later, bob's your uncle, a fully setup XP machine ready to go out the door. Has anybody done this, or know how to? Please let me know how, or point me in the right direction. Thanks. mcurrie111
