How to install Windows 10 on Mac:
Step 1: Launch Boot Camp Assistant. Do a Spotlight Search for it.
Step 2: Check both options under this ‘Select Tasks’ window as shown in the screenshot below.
Step 3: Insert your USB flash drive and select your Windows 10 .iso file, as shown again in the screenshots.
Step 4: Click Continue, you will get a warning saying your flash drive will be formatted. Click on Continue again.
Step 5: Now sit back and wait for Boot Camp Assistant to copy all the required Windows files and Boot Camp drivers to your USB drive. This could take a while depending on the speed of your Internet connection and your computer.
Step 6: Once the USB drive is ready, it will ask you to create a Windows partition. Select at least 30GB for Windows 10 and then click on Install button.
Step 7: Boot Camp will now create the required partition and then it will reboot your Mac.
Step 8. On restart, you will be booted into Windows Setup screen.
Step 9: From here, enter your product key when asked, select your Boot Camp created partition when prompted on where to install Windows. Basically just follow the on-screen prompts to start Windows installation process.
Step 10: Once Windows is installed, your Mac will automatically reboot right into Windows 10.
Step 11: Once you have set up your login account stuff and are in desktop, you will need to install Boot Camp drivers for your Mac. These are the same drivers which were copied by Boot Camp Assistant software to your USB in Step 5 above. Simply navigate to contents of USB flash drive from File Explorer and run setup.exe to install the required drivers for your Mac.
Step: 12: After the drivers are installed and your computer is rebooted, you should now have fully functional Windows 10 running on your Mac.
