Why can't I upgrade to Windows 10 on my Mac?

Episode 1251 (32:36)

Carlos from Santo Domingo

Carlos has been trying to upgrade to Windows 10 on his Mac and it keeps asking for a CD instead of installing with the ISO. Leo says it may be a bad ISO. Boot Camp Assistant will automatically install it. Microsoft will also allow him to download a Windows 10 ISO and it will verify the ISO to be sure it's valid. He can also use this app to download any missing drivers (thanks to Beastmaster in the chatroom).
