We’ll cover everything from creating a bootable USB drive to configuring Windows on the external hard drive. By following these instructions, you’ll be able to have a fully functional Windows installation on your external hard drive.

Before we get started, there are a few prerequisites you’ll need to meet. Firstly, ensure that you have an external hard drive with sufficient storage capacity to accommodate the Windows installation. Additionally, you’ll need a copy of the Windows operating system as an ISO or installation disc, and a Mac running macOS 10.12 or later with the Bootcamp Assistant utility.

Now that you have an overview of what we’ll cover in this guide, let’s dive into the first step: creating a bootable USB drive.

Prerequisites

Before you begin the process of installing Windows Bootcamp on an external hard drive, there are a few prerequisites that you need to fulfill. These requirements ensure a smooth installation and ensure that you have everything you need to complete the process successfully.

1. External Hard Drive: You’ll need an external hard drive with sufficient storage capacity to accommodate the Windows installation. The minimum recommended size is 64GB, but it’s recommended to have a larger capacity if you plan on installing additional software and files on your Windows installation.

Step 2: Partition the External Hard Drive

After creating the bootable USB drive, the next step in installing Windows Bootcamp on an external hard drive is to partition the external hard drive. Partitioning allows you to divide the external hard drive into separate sections, with one section dedicated to the Windows installation.

Follow these steps to partition the external hard drive:

1. Connect the external hard drive to your Mac if it’s not already connected.
2. Open Disk Utility. You can find it in the “Utilities” folder within the “Applications” folder on your Mac.
3. In Disk Utility, select your external hard drive from the list of available drives.
4. Click on the “Partition” tab.
5. Click the “+” button to add a new partition.
6. Adjust the size of the new partition according to your preference. This will be the partition where Windows will be installed.
7. Give the new partition a name and choose the format as “ExFAT” or “NTFS”. Note that if you choose “ExFAT”, the partition will be compatible with both Windows and macOS.
8. Click the “Apply” button to create the partition.
9. Wait for Disk Utility to finish partitioning the external hard drive.
10. Once the partitioning is complete, you can close Disk Utility.

Now your external hard drive is partitioned and ready for the Windows installation. The newly created partition will appear as a separate drive when you boot into Windows.
