How To Fix Boot Camp Error On Mac?

Is anyone having any problems installing Windows using Bootcamp? I keep getting the following error saying it can't partition the hard drive: Boot Camp Assistant was unable to verify if the Windows partition contains a Windows installation. This may be because BitLocker is enabled on the partition. If so, disable BitLocker on the disk before removing Boot Camp. As far as I know I'm not using BitLocker and the FileVault is turned off. Other than the main partition there is a small partition which is 16.8MB which cannot be removed. Any ideas?

Hi there, for the error that occured on your Mac, you're recommended to erase the small partition with 16.8MB size and then install Windows one more time.

Firstly, you need to list all partitions on your device. Launch Terminal and run the command line.

diskutil list

Followingly, erase the partition on your device via Disk Utility.

Finally, Run SMC and NVRAM, and then try to install Windows on your macOS computer one more time. Do not connect any external hard drive to your Mac unless Boot Camp Assistant asks you to do so.
