The message is due to whatever you're trying to boot doesn't contain a bootable operating system. The VM's firmware is iterating across known hardware devices and hasn't come up with anything, so it's trying to boot from the network. In order to get to a solution, we're going to need more information from you about what you're trying to do.
The message has three common causes:
- You didn't install anything to the VM's hard drive. Fusion doesn't provide an operating system for virtual machines, It's up to you to download and install it like you would for a bare-bones physical machine.
- You're trying to boot ISO installation media on Fusion running on M1/M2 Mac that is designed for Intel x64/x86_64 chips. (that is, you've got the wrong ISO architecture ISO to run on arm64 architectures). The solution to this is to make sure that your ISO installer is for arm64/aarch64 (ARM) architectures. not Intel.
- This is a common error if you have downloaded a Windows 11 ISO directly from Microsoft. The fine print there is that ISO is for Intel PCs only (you can thank Microsoft for not having a Windows 11 ARM ISO download). You should investigate the free CrystalFetch app (available in the Mac App store) to download an ARM version of Windows 11 that will work.
- You're trying to install Windows 11 ARM, and missed the "Press any key to boot from CD/DVD" prompt. You don't get very long to do that (you can thank Microsoft for that too). The solution to that is to move keyboard focus to the VM (either by clicking into the VM or typing Command-G) and then pressing any key.
