How can I install Windows 7 on a Windows XP machine?

Episode 1198 (46:06)

Dennis from Santa Monica, CA

Dennis bought a used Lenovo T61 with Windows XP and recovery discs. He bought Windows 7 64 bit and sought to install it, but he can't. Leo says that Dennis may want to try 32 bit instead because of the age of the machine. Leo suggests wiping the drive because XP can't upgrade past Windows 7. So he should wipe the drive and give it a native installation.
