In Previous posts we have covered creating usb boot for fedora & ubuntu.
Apart from unetbootin, you can use UltraISO to create usb boot.
Following is the easy procedure to create bootable usb.
1) Connect USB device & select it int UltraISO.
2) Select Live CD iso image.
3) Click on Bootable from menu, choose Write Disk Image.
From here you can format your USB drive & start writing image by clicking on Write.
Windows Admin can use this tool to write Windows 7 bootable usb (I have not tested on Vista).
And the best part is that, ultraiso supports usb writing in trial version.
