Hi,
At First u need to check whether u're USB drive has the capacity on minimum 1 GB, because the operating itself will carry upto 680MB-700MB of space.So check it out that then restart u're system
Goto the BIOS in advanced tab enable the USB option.
Make the boot from other (in that select the boot from USB )
Then press F10 or whatever the required save button for your BIOS and press enter then it will automatically start loading u're operating system files.
