Install Windows 11 24H2 on Intel MacBookPro 2020 4TB

In case others need them, here are the steps to install the latest Windows 11 (24H2) in Bootcamp.

Due to the macOS 15.6.1 update “bricking” my MacBook Pro, I had to erase my SSD and reinstall macOS, and also reinstall Windows 11 via Bootcamp.

I had previously installed 24H2 by using Rufus and going first from Windows 10 to 11 23H2 and then installing 24H2. This time Rufus just would not work, giving unhelpful errors and finally telling me that my USB sticks were read only (luckily easily fixed by reformatting).

This is a simpler method that uses no third part tools. It’s not a quick process. It should work on any Intel Mac and with the latest versions of Windows 11 24H2, but I have only tested it on mine.

Requirements

Important: When you install 24H2, initially you will not have access to the trackpad or keyboard. You must have an external wired keyboard and mouse, or a wireless keyboard and mouse that run from a dongle (not Bluetooth mice or keyboards) and have already been setup on the same dongle. Once the Bootcamp drivers are reinstalled on Windows 11, your MacBook keyboard and trackpad will again be operational.

Install Windows 10 via Bootcamp

Time: approximately. 30 minutes plus Windows Update time.

1. From Microsoft download Windows 10 22H2 iso file from here: https://www.microsoft.com/en-au/software-download/windows10iso 
2. From Microsoft download Windows 11 24H2 iso file from here: https://www.microsoft.com/en-us/software-download/windows11 (Scroll down to “Download Windows 11 Disk Image (ISO) for x64 devices”)
3. Copy the Windows 11 24H2 iso file to a USB stick (ExFAT format).
4. Launch the Bootcamp Assistant app 
5. From the menu bar, choose Action and select Download Windows Support Software.
6. Save this to a new folder on your Desktop or any other convenient location. You will need these files later after installing 24H2.
7. Copy the Windows Support software to a USB stick (ExFAT format). 
8. In the Bootcamp Assistant app, click <Continue> and browse to the folder where you have saved the Windows 10 23H2 iso file and select it.
9. Follow the Bootcamp installation process. Note that it will download Windows Support files again - this is normal. Once the Windows installation is complete, the app to install the Bootcamp drivers will automatically launch.
10. In Windows, run the Apple Software Update app. This will install updates 6.1.13 and 6.1.14. Restart Windows.
11. Again, in Windows, run the Apple Software Update app. This will now install updates to version 6.1.17 and 6.1.19. Restart Windows.
12. Launch Windows Update and install any updates found.
13. After restarting Windows, check Windows Update again. Repeat until there are no further updates to install

Install Windows 11 24H2

Time: approximately. 40 minutes plus Windows Update time.

1. Launch Windows and copy the Windows 11 24H2 iso and the Windows Support Software from the USB stick(s) to the desktop.
2. Plug in your wired keyboard and mouse (or wireless mouse/keyboard USB dongle)
3. Double-click the iso file to mount it and note the drive letter Windows assigned to it. I will assume it is “D.”
4. Use the taskbar search to find “CMD”, choose the (Admin) or Run as Administrator option to launch the CMD console.
5. Type in D:\setup.exe /product server and press <Enter>.
6. The Windows installation will start. 
7. On the “Install Windows Server” pane, click the link “Change how setup downloads updates” and choose “Not right now” and click <Next>.
8. On the “Choose what to keep” pane, select the option best for you. If you installing from Windows 10 already in use with apps and personal files etc, choose to keep them, otherwise just choose “Keep personal files only” and click <Next>.
9. After logging in to Windows 11, check that your Windows Support files are still there (they may not be, and if not, copy them from your USB stick), then in the Bootcamp folder, double-click setup.exe. The Bootcamp drivers will now install. Restart Windows.
10. In Windows, run the Apple Software Update app. This will install updates 6.1.13 and 6.1.14. Restart Windows.
11. Again, in Windows, run the Apple Software Update app. This will now install updates to version 6.1.17 and 6.1.19. Restart Windows.
12. Launch Windows Update and install any updates found.
13. After restarting Windows, check Windows Update again. Repeat until there are no further updates to install.
