bootcamp is not runnng on my macbook air

Hi shambhu5365,

Does your MacBook Air have an M-series chip? If it does, unfortunately Boot Camp is not supported. This is because M-series Macs use a different hardware architecture than most other computers, and Apple & Microsoft would have to write custom drivers to support running Windows natively.

To check if your Mac has an M-series chip (is Apple Silicon), click the Apple logo in the top left corner, choose About This Mac, then compare the info shown to the list here: Mac computers with Apple silicon - Apple Support (CA)

If your Mac has an M-series chip, you can still run the ARM version of Windows in a virtual machine. Several options are available for this, including UTM, Parallels, and VMware Fusion.

If your Mac has an Intel processor instead, please let me know and post a screenshot of the error message that appears: Take a screenshot on Mac - Apple Support (CA)

Since you must be on an Intel architecture Mac (because Boot Camp does not install on Apple Silicon Macs), you should review the current:
