How can I reinstall Windows?

Episode 1124 (2:02:35)

Stephanie from Los Angeles, CA

Stephanie bought a Samsung Windows 7 notebook and it's been a disasterous affair. She wishes she had bought a Mac. Leo says that Apple has a much better way to teach users how to use computers with their One to One teaching. She tried to get tech support with a phone number given to her from friends who used remote desktop and now she got infected. Can she wipe it and start over? Leo says sure, if she has a system recovery disc that came with the computer. She should get her data off first, then wipe the drive and reinstall Windows. And she should make sure she updates it completely.

Leo also says that by partitioning her hard drive and putting the data on the second drive, she can wipe the C drive and start over without affecting her data drive.
