Some users complain about a partitioning error they encounter when using Bootcamp on their Mac. The error reads ‘An error occurred while partitioning the disk’. In this article, we provide some insights on troubleshooting the error. Read on to learn more.
For reference, Bootcamp is a utility that allows Mac users to install a Windows OS on their systems.
Solution 1: Repair Disk
An error with partitioning disk may sometimes arise if there are issues with directories or file systems. To resolve the issue, go ahead with the following steps.
Before you begin, make sure you have a backup of your data. Nothing may happen, but it is always a good idea to be prepared.
- Go to Applications > Utilities > Disk Utility
- Click on your hard drive on the left pane
- Select Verify Disk to begin the checking your disk
- Wait for the process to complete and produce a status report. If any errors are found, click on Repair Disk to repair your disk
If the procedure is successful, all errors will be fixed and you can now try running Bootcamp again. If it works, great! If not, try running FSCK as explained in the next section.
Solution 2: Run fsck
This is used to verify system files and fix any corruption. Running this trouble-shooter should be done through command prompt. It may sound complicated and technical, but don’t let it. Just follow the instructions below and you should be fine.
- Restart your Mac and boot into single user mode by holding down Command + S
- You will enter the command prompt, where you are required to type “/sbin/fsck-fy”
- This command will verify and repair corruptions if any. Once the process is complete, type “exit” to exit from the command prompt.
Now start your Mac as usual and try running Bootcamp. This should resolve the issue for you. If it doesn’t, proceed to the next step.
Solution 3: Switch off File Vault
File Vault on a Mac system is used to protect data, but this can at times create problems with BootCamp. So, try disabling FileVault to fix issues. To do so, please follow the steps below.
- Go to Applications > System Preferences
- Click on Security & Privacy > File Vault
- Enter the administrator details and finally click on Turn off FileVault
This will stop your Mac from encrypting your start-up disk and help you resolve the issue with partitioning. Try running Bootcamp again and check if the issue is resolved.
If none of these solutions fix the error, you will have to reinstall Mac OS completely. This is an extreme step, however, in most cases, Repair Disk or FSCK will resolve the issue.
In some cases, while performing Verify Disk or FSCK, you may lose important data on your system. If you don’t have a backup and you need to recover data from corrupted Mac Volume, data recovery tools such as Remo Recover can be useful. Its hard drive recovery tool can perform recovery of partitions and data from the drive.
