Windows XP (the OS) doesn't boot from USB or Firewire today.
It's a Microsoft thing (decision.)
Running WinXP Home Ed., P4, 3 Ghz on Desktop. Purchased an external usb 2.0 HD. Put an OS on it. Want to boot to it. No can do. The BIOS supports a boot sequence to a USB HD. The drive appears in My Computer and the Disk Management utility in Win XP. Will only boot to original C drive. Are these drives designed for storage only? Any advice appreciated.
