Since most likely it won't work, even if you can boot from it, I don't think it's a serious problem.
- Why do you want to run XP on your new laptop?
- And do they really still sell new laptops with Windows 7.
My old Windows XP laptop finally died. I put the hard drive in an external enclosure and attached it to my new Windows 7 laptop via USB. Changed the boot order to the external device and restarted but it still boots to Windows 7. What am I doing wrong???
