Back up your Mac and any important Boot Camp data
Open Boot Camp Assistant
Click Continue
Select Remove Windows 10 or later version
Click Restore
If Boot Camp Assistant says there is not enough free space, restart your Mac
Hold Option and boot into macOS only
Open Disk Utility
Select the internal drive, not just a volume
Click View
Choose Show All Devices
Check for APFS container and partitions
If needed, use Terminal to verify disk layout with `diskutil list`
Make sure macOS is on the internal drive and Boot Camp is the partition to remove
If Time Machine local snapshots are using space, delete them
Open Terminal
Run `tmutil listlocalsnapshots /`
Delete snapshots with `sudo tmutil deletelocalsnapshots
Empty the Trash
Free additional disk space in macOS
Restart the Mac
Run Boot Camp Assistant again
If Boot Camp Assistant still fails, use Disk Utility to erase the Boot Camp partition only if it is clearly labeled as Windows/BOOTCAMP
If the partition cannot be removed in Disk Utility, use Terminal carefully with `diskutil apfs deleteContainer` only when Boot Camp is confirmed as the target
If the disk is encrypted or the partition table is damaged, repair the disk first with First Aid in Disk Utility
If the issue persists, reinstall macOS recovery tools or contact Apple Support
