Catalina Bootcamp Windows 10 Error

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

You need an external USB drive to install Windows on older Mac computers. To find out whether you have a Mac that requires an external USB drive, see the “Learn more” section in the Apple Support article Install Windows 10 on your Mac with Boot Camp Assistant. If your Mac is a newer model that doesn’t require a USB drive, follow the instructions in Install Windows on your newer Mac using Boot Camp instead.

What you need

• The keyboard and mouse or trackpad that came with your Mac. (If they aren’t available, use a USB keyboard and mouse.)

• A blank 16 GB or larger external USB 2 flash drive, formatted as MS-DOS (FAT).

  To format an external USB drive as MS-DOS (FAT), use Disk Utility, located in /Applications/Utilities. In Disk Utility, choose View > Show All Devices, select the USB drive in the sidebar, then click Erase in the toolbar. In the dialog, enter a name for the drive, choose MS-DOS (FAT) from the Format pop-up menu, choose Master Boot Record from the Scheme pop-up menu, then click Erase.

• A full-installation, 64-bit version of Windows 10 on a disk image (ISO file) or other installation media.

  You can download a Windows 10 Disc Image (ISO File) from Microsoft.

Perform the installation

Do the following steps in order.

Step 1: Check for software updates

Before you install Windows, install all macOS updates.

1. On your Mac, log in as an administrator, quit all open apps, then log out any other users.

2. Choose Apple menu > System Preferences, click Software Update, then install all available updates.

6. At the Create a Partition for Windows step, specify a partition size by dragging the divider between the macOS and Windows partitions. If you have multiple internal hard drives, you can select a different hard drive from the one running macOS and create a single partition on that drive to use solely for Windows.

When this step is complete, the Windows installer starts.

   If nothing appears to be happening, there may be a hidden window that you must respond to. Look behind open windows.
