Hello, somehow inspite of Terminal methods and USB refresh apps (for weeks, many man hours), macOS Monterey won't mount any external drives (it does mount the internal drives), now I plan to burn my older macOS (like High Sierra which has been the most stable macOS by far) installer as a bootable flashdrive so I can partition and install an older macOS to see if it's truly macOS Monterey because Windows (Boot Camp) mounts external drives with no problems and also a backup macOS installation but is there an app on windows that can burn onto a flashdrive and make bootable a macOS that's .dmg, .esd or .cdr (preferably freeware).

Thank you in advance.
