Re: T420s will not boot to USB jump drive

I am not sure why you'd want to boot from a USB 2.0 port, its quite slow. The eSATA is much better suited.

If you go into the BIOS and change the boot order so the the USB port is above the DVD or Sata HD it should boot. Thats the way all other systems work. Nothing to do with the splash screen etc.
