|Did you use the Dell cd to create this? If so you might need a real xp cd. Dell doesn't offer complete cd's.|
Could make a barts 2 usb and use it's tools to load disk from networked shared cd with the dell cd in it maybe. Or put the image of the cd or contents on the flash with barts.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, Make an autorun.inf folder on all usb drives.
