When you try to install Windows on a Mac using Boot Camp Assistant, you may get the following error message: "Boot Camp Assistant Quit Unexpectedly." This error can be caused by a number of factors, including outdated software, corrupt files, and incompatible hardware. Here are some tips to help you avoid this error and successfully install Windows on your Mac.
How to Fix the “Boot Camp Assistant Quit Unexpectedly“ Error
If you see the error message "Boot Camp Assistant Quit Unexpectedly" when trying to install Windows on your Mac, there are a few potential solutions you can try to fix the problem.
Fix 1. Upgrade Your Boot Camp Assistant
One of the most common causes of the "Boot Camp Assistant Quit Unexpectedly" error is outdated software. Be sure to update both your Mac’s operating system and Boot Camp Assistant to the latest versions before attempting to install Windows. You can update your Mac’s software by opening the App Store and clicking the Updates tab. To update Boot Camp Assistant, open the program and click the Check for Updates button.
Fix 3. Check for Corrupt Files
If you‘re still seeing the "Boot Camp Assistant Quit Unexpectedly" error after updating your software, it‘s possible that some of the files required for the installation are corrupt. To fix this, try running the Boot Camp Assistant repair tool. To do this, open Boot Camp Assistant, click the Utilities menu, and select the "Repair Boot Camp" option.
Fix 4. Reset the NVRAM on Mac
If you are already using the latest version of Boot Camp Assistant, the next thing to try is resetting the NVRAM on your Mac. NVRAM is a type of memory that stores certain settings and preferences, and resetting it can often fix strange problems like this one.
- To reset your NVRAM, shut down your Mac and turn it on again.
- Immediately press and hold the Option, Command, P, and R keys.
- You will need to keep holding these keys until your Mac reboots and you hear the startup sound for a second time.
Fix 5. Uninstall Any Virtualization Software
If that doesn‘t work, try uninstalling any virtualization software (such as Parallels or VMware Fusion) that you have installed on your Mac. These programs can interfere with the Boot Camp installation process. If you‘re still having trouble, it‘s possible that there are some bad sectors on your hard drive. To check for this, you can use the Disk Utility program that comes with your Mac. Just launch Disk Utility, select your hard drive, and click on the "Verify Disk" button. If Disk Utility finds any problems with your hard drive, it will ask you if you want to repair them.
Fix 6. Create A New Partition on Hard Drive using Disk Utility
If resetting PRAM doesn‘t fix the problem, you can try to create a new partition on your hard drive using Disk Utility.
- Step 1. To do this, open Disk Utility (it‘s in the Utilities folder in your Applications folder).
- Step 2. Select your hard drive from the list on the left. Click the Partition button and then click the + button to add a new partition.
- Step 3. Give the partition a name, choose a format (MS–DOS (FAT) is fine), and make sure the size is correct.
Once you‘ve created the new partition, try running Boot Camp Assistant again and see if the error is gone.
Fix 7. Creating A New Bootable USB Drive
The next thing to try is creating a new bootable USB drive for your Windows installation. Sometimes the problem can be caused by a bad or corrupt USB drive. To create a new bootable USB drive, you will need a USB drive that is at least 8 GB in size. If you don‘t have one, you can buy one from any electronics store. Once you have the USB drive, open Boot Camp Assistant and click on the Action menu. From there, select "Create a Windows 7 or later version install disk." Follow the prompts to select your USB drive and start the Windows installation. Once the installation is complete, you should be able to boot into Windows without any problems.
If none of the above solutions work, you may need to contact Apple support or take your Mac to an Apple Store for further assistance.
