I was trying to install Windows 10 besides my Mac OS X El Capitan. I followed the normal steps I found on the Internet, but when I started to apply I got this and no idea what I should do in order to install Windows.
After I click continue, I choose which USB to save the downloaded file on, and then nothing changed; I still can't finish the process of pointing to an ISO image of Windows 10 that I want to install.
Note: my MacBook Pro is manufactured I think in 2010/2011. It's a Core i5, 4GB RAM.
Windows 7 was installed on it besides my El Capitan OS X a month ago, and BootCamp was deleted by my son.
