it says bootcamp does not support the version of my device

You’re using an Arm AArch64-based computer with an Apple silicon M1 processor.

Not an x86-based (technically x86-64) computer with an x86 processor from Intel, AMD, or another x86 processor manufacturer.

Apple is the manufacturer of M1 processors, and Apple uses the Arm AArch64 architecture for M1. Not x86.

The most familiar version of Windows is available for x86-based computers that can present themselves as a PC, and a separate version of Windows is available for some Arm systems based on Snapdragon Arm processors.

Boot Camp causes an Intel x86-based Mac to present itself to Microsoft Windows as an x86 PC.

You have an Apple M1 Arm AArch64-based Mac, and not an x86-based Mac.

Boot Camp does not emulate an x86-based computer on an Arm AArch64-based computer.

(Emulation is a means for executing hardware instructions for one computer architecture on a different architecture. This distinct from virtualization, which presents part of the resources of the available computer hardware as an additional computer. Virtualization doesn’t try to translate instructions as does an emulator, as that hardware instruction emulation process is slower and more resource-intensive.)

Arm AArch64-based operating systems for Apple M1 are available including macOS, and with more becoming available.

A released version of Microsoft Windows for M1 Arm AArch64-based computers is not currently available, but some folks have gotten a Microsoft Windows AArch64-based beta to work.

The folks that provide the Parallels virtualization app have indicated they plan to support running Windows Arm AArch64-based version on Mac M1 systems with Parallels 17.

Windows for Arm AArch64 can reportedly emulate x86 app code for Windows, with the current beta. Yes, macOS and Windows apps are also architecture-specific. Apple emulates macOS x86 apps on macOS on M1. Microsoft provides similar support for Windows x86 apps on Windows for Arm AArch64-based systems with the beta.

To run Windows for x86 on Apple M1, you’ll need a solution including an emulator. Boot Camp does not provide the needed emulation.

We’ll probably know more about any Microsoft plans here when Windows 11 is announced next month; with the first of the Windows 11 announcements planned for October 5th.

If you need Boot Camp, or need to run an operating system such as Windows for x86, you’ll need an Intel-based Mac.

Details from Apple:

Install Windows 10 on your Mac with Boot Camp Assistant - Apple Support

Mac computers with Apple silicon - Apple Support

Unlike older Intel Macs, new M1 Macs do not support current mainstream Windows and vice versa.
