Or just use Rufus[1] to create a bootable USB installer from the ISO.
Another trick that should still work, though I haven't tested it with newer Windows 11 builds: to create Windows 11 install media that will install and boot via BIOS — useful on machines where Windows doesn't work correctly under UEFI, e.g., older MacBooks that only work properly with Windows when booted via CSM — create writeable, BIOS-bootable Windows 10 x64 install media, then replace the install.wim file with one from an appropriate Windows 11 ISO.
