How to Install Windows 10 on Mac Without Bootcamp

There are many options when it comes to installing and running Windows 10 on a Mac computer. One of the most popular options is to use Mac OS built-in Boot Camp Assistant software.

But unlike the other apps that come with Mac OS, Boot Camp has a couple of drawbacks regarding its performance and functionality. Such as,

  • It currently supports only a single partition drive.
  • Often gives unknown error messages with minimal information.
  • Every time it launches, it will automatically download 1.6 GB windows drivers. And it is placed under “/Library/Application Support/BootCamp/WindowsSupport.dmg”.

So in this article, we will teach you how to install windows 10 on Mac OS without using a Boot Camp.

Install windows 10 on mac

What you will need

  • A USB Stick (8GB or larger)
  • A Valid Windows 10 license
  • A copy of the Windows 10 ISO
  • A Downloaded copy of the unetbootin

Step 1. Turn on your Mac device normally and boot into Mac OS. Then open the Launchpad and click on “Other”. From that list open Disk Utility.

Step 2. In the Disk Utility, on the left side select your drive (SSD or HDD). After that select the partition tab. Here Disk Utility will show you the layout of the partition.

Step 3. To create a new partition, click on the small “+” sign.

Step 4. Select the new partition that you have created and enter a name for it. (Remember to enter a name that you can easily recognise later when installing the Windows 10). Select the size of the partition (minimum size should be at least 30 GB). And finally, select the partition format. (Choose either ExFat or DOS here, remember you have format the partition as NTFS later when installing the windows 10).

Step 5. After entering all the required information click on the Apply button. When you see the following error message click on the Partition button. Once the new partition has been created, close the Disk Utility tool.

Step 6. Now, you need to create a bootable Windows 10 installation media. If you already have a Windows 10 bootable media, you can skip Step 7 and proceed to step 10.

Step 7. Plugin your USB Stick and start Disk Utility. In the left panel under external, select your USB device. Click on the Erase option and select all the options as follows. Then click on Erase.

Name: FAT32

Format: MS-DOS (FAT)

Scheme: Master Boot Record

Step 8. Download and install “unetbootin” from the following web link. (It’s free open-source software). https://unetbootin.github.io/

Step 9. Plugin your USB Stick and start unetbootin (Enter your password here if required). Then select all the options as follows and click OK. (It may take a few minutes to complete this process)

Disk image: Check the Diskimage option and browse and select your Windows 10 ISO file.

Type: USB Drive

Drive: Your USB drive (you should only see one drive here, if you have multiple drivers listed here, confirm the right device before selecting the drive)

(* Before Step 10 it is crucial to disconnect all the external drives which are connected to the machine. Unplug everything except your keyboard. Also if you have multiple drives connected, disconnect them all except the one which you want to install the Windows 10)

Step 10. Once your bootable media drive is ready, Restart your mac and while restarting hold down the “ALT” (Option) key. This will bring up the following screen. Here select the Windows option. (Only select EFI if you are certain)

Step 11. Select the newly created partition in the following partition selection screen and click on the Format button to format the new partition with NTFS. (Remember to make sure whether you have selected the right partition before clicking on the Format button.)

Step 12. Then click on the Install button. It will take a few minutes to complete this process. (Note that during Windows 10 installation, your machine will restart several times. Remember to hold down the ALT key and select the Windows in the option to continue the installation.)

Step 13. From here onwards, you will need to follow the standard Windows 10 installation procedure.

Step 14. Once the installation is completed, make sure to check whether everything works fine.

That’s it. If you find any problems when you do the installation feel free to mention them in the comment section. We are here to help you.
