How do I remove this partition (Unallocated space)

I recently tried deleting my Boot Camp partition, so I can reinstall it with more memory and windows 11 (Read its possible in this article https://machow2.com/windows-11-mac-boot-camp/). One Month ago I reset the macOS partition which made the windows partition no longer show up in the Boot Camp Assist and could therefore not be deleted. I tried to delete the partition with the disk utility program and now I have unallocated memory on my hdd. When I try to remove the unallocated memory it just gives me error messages.

When I run diskutil list it gives me this:



It would be great if someone could help me to make a single partition and to reinstall windows.

That's the issue. Using Disk Utility, instead of Boot Camp Assistant, to remove the partition doesn't work. Your best bet is to back up your Mac with Time Machine, then erase it and restore from the backup.


  1. Back up your Mac with Time Machine - Apple Support
  2. Use Disk Utility to erase an Intel-based Mac - Apple Support
  3. Restore your Mac from a backup - Apple Support


Additionally, Windows 11 isn't officially supported. While it's true that some have managed to get it working, you may encounter issues that could be difficult to diagnose.
