How to Install Windows on a Mac without Bootcamp Assistant?

I currently own a Mac and would like to install the Windows operating system on it. However, I want to explore alternative methods as I'd like to avoid using Boot Camp Assistant, the default utility provided by Apple for this purpose. Unfortunately, I'm unaware of any other reliable methods or tools to accomplish this task.


Hence, I kindly request your assistance and expertise in guiding me through the process of installing Windows on my Mac without using Boot Camp Assistant. I understand the importance of compatible software and the potential risks involved in altering the operating system, so I seek lawful and secure methods only.

When you post a question such as yours, it would serve you better to state that you have an Intel or Apple Silicon architecture Mac running a specific operating system version. That reduces the fishing expedition as to what specifically will work in your case.


I use the current version of Parallel's Desktop Pro 19.3.1 on an 8-Core, Core i7 27-in 2020 iMac. Parallels charges me around $120/yr subscription and I have Windows 10 22H2 and Windows 11 Pro 22H2 guests. Those guests are installed on an external Crucial X8 SSD (1050 MB/s) connected to my Thunderbolt 3 port. The iMac is running macOS Monterey 12.7.5.


Microsoft has only publicly sanctioned Parallels for running Windows 11 ARM on Apple Silicon Macs. VMware is now offering a free, non-commercial user license for their Fusion VM client, but very likely will want personal information that at minimum may result in ramped email SPAM. Nothing is truly free with these vendors.


The free Oracle VirtualBox VM is only compatible (their current data) with Intel Macs running Monterey or earlier. I quit using VirtualBox after several years for Parallels Desktop.


Stack Social has Windows 11 Pro licenses in the $25 range (today) and you should have a Microsoft account because an aspect of the purchase process requires one to sign into a Microsoft account so the license purchase is registered with Microsoft. I purchased Office 2021 for Mac and Office 2021 Professional Plus for Windows through them and never paid more than $35 each.


Microsoft Windows licenses are platform-agnostic and can be used for ARM or Intel.

No one looking to get help with bootcamp is running it on an Apple Sillicon Mac, so that’s moot and not worth mentioning.

Running with bootcamp is the only “real” way to go. Parallels is a joke and breaks compatibility with many applications and software, let alone games, which is what I’m trying to use Windows on this Mac for. One really needs to run Windows on bare metal (not the API), and I don’t think parallels can do that, and since this discussion is about bootcamp, there is no reason to entertain such software.

Actually this thread was started by someone asking how to run Windows WITHOUT bootcamp. And that person never clarified what type of machine they had. Therefore, it's perfectly reasonable for people to ask you for more details about what you're asking. Remember, everyone here is a voluteer.

If they’re asking about bootcamp, help them with bootcamp. Chances are they’ve checked compatibility before trying to ask for help. I know I would have.

What you would do and what someone else with different knowledge and experience might do are not necessarily the same. It doesn't do make assumptions here. Give that the original poster never posted again, we don't know what they wanted.


If you need help, I suggest you start your own thread as it appears that any issues you may have are different than the original poster. Also, posting in old threads is rarely as effective as starting a new one.


And, as I said, the thread was about using Windows WITHOUT Bootcamp.

I’m trying to install Windows WITHOUT bootcamp. Yes. Like I said, boot camp assistant checks for various things before letting the user… use it. My machine failed the more than 1 partition check, but I need to install Windows anyway. That is the problem I am having, and it’s in the same basket as OP’s. Installing Windows without the use of the boot camp assistant.

I suggest you start your own thread. You will get more and better assistance.

People have gotten Windows to work on Intel Macs without the use of Bootcamp, so I know it’s possible, I believe this is basically how it was done originally, when bootcamp was in its infancy, it used to be a lot more manual.

I know it can be done, we- ok maybe not we, but I, myself, am just looking for the instructions on how to do it.

In other words, you're looking for someone to redo all the work that Apple did for you in creating Boot Camp – which will likely turn out to involve creating new drivers for all of the pieces of Apple hardware that Boot Camp would have provided Windows drivers for?


Just because Windows (apparently) doesn't play very nicely with partitioning?

uh… no..?

The drivers have absolutely nothing to do with my inquiry. I’m sure they’d work perfectly after installing Windows. The problem is getting to that point. I am able to partition the drive but then Windows will complain that it’s a GPT or an MBR… whatever I have basically it wants the opposite one when installing Windows manually (not through boot camp), but with bootcamp it’s fine somehow. I just need to know how to do that myself, and the problem will no longer exist.

Thanks for the info, but I very much understand what drivers are and how they work. Apple provides Windows drivers for their Mac computers, and there is no reason for those drivers to not still work, therefore it’s not an issue. Drivers aren’t the problem. It’s getting Windows on the machine at all. Boot camp as dumb limitations like not being able to use it if you have more than 1 OS installed, which I almost always have 2 installed, one that is closer in release to when whatever machine it is was released, and one that’s one of the newest possible MacOS that it can run. Boot camp makes installing Windows on these systems a pain, and I basically have to throw away one of the two already installed OSs. This is why I am asking for a solution to this problem, as I’ve had to do this dance on many Macs, and I’d much rather just do it manually instead of having to rely on Boot Camp Assistant.


I’d appreciate it if you assumed I know a lil more than you appear to think, and provide a solution to this problem. Thanks.

Actually you can download the drivers completely separately from Boot Camp Assistant, it still includes the “boot camp” drivers and software for the Windows side, and works perfectly fine that way. I’ve had to do this a few times in the past when the assistant just didn’t work. Apple has made it a pain to locate the download links for these drivers, and there’s a few different “versions” depending on what machine is being worked on, but they all can be downloaded separately. There’s also an option in newer versions of Boot Camp Assistant to just download the drivers and dump them onto your disk for

copying onto a flash drive or something yourself. It all works, and this has never been a problem for me.


As I’ve said a few times so far, the problem isn’t the drivers. It’s getting the actual Windows partition to exist and to have Windows install on it, which I have always been unsuccessful at, but I know it can be done, as boot camp assistant does it. I just need to know how it does that, so that I can do it myself.


I have Googled how to install Windows without boot camp assistant (or something very similar), and that’s what has brought me here.


I also think the reason why I keep having to repeat myself here is because of the strange and annoying layout this forum seems to have. Messages I’m responding to on the 3rd page (here) are actually on the 1st page even though they’re brand new. That makes no sense. I’m not a big forumite but even I know that’s not how forums should work..

Edit: It’s because the default sorting is “Rank” for some reason. Hopefully that helps someone.

Ah, ok. Seems legit.

I have about 20 machines ranging from 2006-2019 I want to do this on, so yea for some of those that is spot on. That example was a 2011 17-inch MacBook Pro.


hmmm hybrid partition scheme… that sounds very promising. I did try installing each one manually, and first installing Windows, then making partition(s) for MacOS to be installed on, but as soon as I Installed MacOS, Windows would no longer show up as a boot option.


Well I love Windows 7 so that’s awesome. I doubt that would work on Macs from 2009-before, since UEFI was like 2010-onward I think for the most part. These ones are what I am most interested in doing this to though, so that’s fine.


I wish I could use a FireWire 800 drive to install old crusty MacOS, then I could use it with… 80% of my machines really, but I recall the last time I tried this, the installer complained about it being a FireWire drive and would let me.


If I am successful in my quest, I’d have to make a video on it, and a guide for it. I’ll dig up some old crusty documentation, something’s gotta work.


Thanks for this, much appreciated.
