Question: How can I install windows os on my macOS system

You can use Boot Camp Assistant to install Windows 10 on your Intel-based Mac.

Depending on the model of your Mac, you might need an external USB drive to install Windows. Newer Mac models—with OS X 10.11 or later—use the internal drive to temporarily store the items you need to install Windows and don’t require a USB drive.

On your Mac, do the following steps in order to perform the install.

Step 1: Check for software updates: Before you install Windows, install all macOS updates.

Step 2: Prepare your Mac for Windows : Boot Camp Assistant prepares your Mac by creating a new partition for Windows named BOOTCAMP and downloading the Boot Camp support software.

Step 3: Install Windows : In the Windows installer, follow the onscreen instructions.

Step 4: Install Boot Camp on Windows : After installing Windows, Boot Camp drivers that support your Mac hardware start installing.
