Why Not Use Boot Camp?
Until the release of Apple Silicon M1 Macs, Boot Camp was one of the most popular ways to install Windows on a Mac, especially for gaming.
However, Boot Camp has quite a few disadvantages when it comes to installing and running Windows on a Mac.
One of them is that you can only boot your Mac in Windows on macOS using Boot Camp. You can’t run them at simultaneously like you can with a virtual machine.
Another big problem is that the latest M1 chip Macs do not support Boot Camp so you can’t install Windows on an M1 Mac with it.
Boot Camp also requires a lot of hard drive space on your Mac to install and run Windows plus games or applications that you want to use with it.
The best way to install Windows on a Mac is using a virtual machine such as Parallels which is easily the best alternative to Boot Camp.

However, if you want to keep your Mac and Windows files truly separate or don’t have enough hard drive space on your Mac’s internal hard drive, then an even beter way to install Windows on a Mac is by using an external hard drive to run Windows.
This also has the advantage that Windows does not take-up any of your hard drive space on your Mac’s hard drive as it’s all stored and run on an external drive.
The other great thing is you can install Windows on a Mac for free nowadays.
You only have to buy an activation key for Windows 10 or Windows 11 if you want to remove a small watermark from them and customize them.
Can You Install Windows on an M1 or M2 Mac Without Boot Camp?
Unfortunately the following instructions to install Windows on a Mac without Boot Camp only work on Intel Macs.
Apple Silicon M1 and M2 Macs have advanced security protection that won’t allow you to boot from an external drive.
However, you can still install Windows on an M1 Mac without Boot Camp by using Parallels instead.
How To Install Windows Without Boot Camp
With this in mind, here’s how to easily install Windows on a Mac without Boot Camp for free.
1. Get an External Hard Drive
The first thing you’ll need to install Windows without Boot Camp is an external hard drive.
If you don’t already have one, there are several Mac compatible external hard drives that work best and we strongly recommend choosing a Solid State Drive (SSD) which is much quicker than a mechanical hard drive because it has no moving parts.
Speed is extremely important when trying to run Windows from an external drive on your Mac.
The best SSD external drive for Mac is the Samsung T7 Portable SSD which is available with up to 2TB of storage space which is more than enough to run Windows from and install Windows updates, games and apps.
Remember that you’ll need to format the external drive for your Mac before your Mac will recognize it.
We also recommend either using a second external hard drive or pen drive to transfer the Boot Camp support files from your Mac to Windows during the installation process.
2. Get an External Keyboard & Mouse
You’ll also need access to an external keyboard and external mouse as the first time your MacBook boots into Windows, the keyboard and Trackpad on your Mac will not work because there will be no drivers.
Any USB connectable keyboard or mouse will work but don’t get one that only has Bluetooth connection as Windows will not be able to use your Mac’s Bluetooth card initially.
3. Download a Windows ISO File
A Windows ISO is a Windows file that allows you to create a bootable drive to run Windows 10 or 11.
You can download both a Windows 10 and Windows 11 ISO from the Microsoft Software Download site.
You can get find out how to download a Windows ISO on your Mac here.
4. Download Etcher
Etcher is a clever utility that allows you to mount and install a bootable version of the Windows ISO on an external hard drive.
There are many utilities to create an external boot drive on Windows such as WinToUSB and Rufus. However, many of them are PC only but Etcher also works on Mac.
There are also other disk boot utilities such as UNetbootin and Disk Utility X but they haven’t been updated to work with the latest versions of macOS Big Sur and Monterey.
Etcher work on the latest versions of macOS Monterey and is very easy to use.
5. Disable T2 Chip Security
Now you’ve got the essential equipment, you need to start preparing your Mac.
On your MacBook, you then need to disable the security features of the Apple T2 chip.
The T2 chip prevents you from booting your Mac from an external drive so you need to disable this feature in the Mac Startup Security Settings.
It’s only possible to disable this on Intel Macs which is why this way of installing Windows without Boot Camp does not work on M1 chip Macs.
To access your Mac’s Startup Security Settings switch on your Mac and hold down the Command and R keys until you see the Apple logo.
In the recovery space that appears, go to Utilities > Startup Security Utility from the Menu Bar. You must then check the boxes:
- Under Authentication select “No security”
- Under Secure Boot select “Allow booting from external media”
Then close the security settings and go to the Apple logo to shut down your Mac as normal.
6. Download Windows Support Drivers
At this point, you need access to download the Windows Support Software which provide drivers to run Windows on a Mac.
Normally Boot Camp does this automatically but since we’re not using Boot Camp to install Windows here, you can also download the Windows Support Software from Apple.
You then need to drag and drop the Windows Support Software you’ve downloaded onto an external drive such as a USB pen drive.
If you have any problems downloading the Windows Support Software check here.
7. Create a Windows Boot Drive
Open the Etcher USB boot utility that you downloaded earlier and make sure your external hard drive that you want to install Windows on is connected.
Simply select the Windows ISO image that you downloaded earlier, select the external drives and Etcher will create a bootable Windows drive on it.
The installation process should take around 10-15 minutes to complete.
Finally, you need to copy the Boot Camp support files you downloaded earlier onto the root of the external drive and shut down your Mac.
8. Boot Windows From Your External Drive
Finally, you can now boot Windows on your Mac from the external drive.
To do this, switch on your Mac and hold down the Option key when you see the Apple logo.
Select the external drive with Windows on to boot from.
Because Windows doesn’t have the drivers to use your Mac’s keyboard or Trackpad, you need to connect your external keyboard and mouse to a USB port on your Mac.
When the keyboard and mouse are connected, browse to the C drive in Windows and go to the Windows Support folder.
Launch the Boot Camp setup program and it will automatically install the drivers for your Mac’s keyboard and Trackpad.
You’ve now installed Windows on an external drive to use on your Mac without the need for Boot Camp.
You may notice that Windows runs a little slow on your external hard drive, even on an SSD drive. This is because the read-write speeds of external drives aren’t as good as internal drives but it’s still more than usable.
WTF? Step 6 involves using bootcamp. This article is about installing without BC.I don’t have BC or MacOs.
You need to download the Windows Support software from Boot Camp as they are no longer available from Apple. Once you’ve got them however, you no longer need to use Boot Camp to install Windows. If you’re having problems downloading the Windows Support Software with Boot Camp check here.
What part of “without Boot Camp” do you not understand?
I have two Macs. One is too new to have Boot Camp, the other 2010 model has no OS and I can no longer reinstall thanks to Apple policies.
You should explain how to get the Boot Camp drivers without. Boot. Camp.
You can now download the Windows Support Software (also called Boot Camp Software) from Apple here.
This doesn’t work in November 2022. I’m running Big Sur on a 2020 MBP. Followed instructions and I think it must be missing steps or some important detail. Is there a workaround for Etcher? Between July and now, that program has changed and I cannot find the beta version shown in the screenshot here. Once it has done what it is supposed to do, you cannot drag the Bootcamp support files onto the drive, as it is no longer mounted and showing via finder. I skipped that step regardless and tried to boot from the Thunderbolt based ssd and it doesn’t show up as an option. I’ve spent literally hours trying this and a different tutorial with no luck. I appreciate your time putting this out here. Just wish I could get it to work out.
It is still working. Have you formatted the SSD drive so that your Mac can recognize it?
Can I install windows on Mac and partition it first b4 installing mac os in the other partition please??
Yes you can create a partition and then install another version of macOS on it if that’s what you mean.
its funny cause the title says without boot camp and this mf did it the boot camp way
