When you are creating your USB Bootable for Mac OS Mojave or whether it is Windows 7/8/8.1 or Windows 10 it means you don’t need any CD/DVD that should support you to install the operating system on your computer. When we are creating bootable USB.
These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
Find the appropriate download link in the upgrade instructions for each macOS version:
macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. * If your Mac is using macOS Sierra or earlier, include the --applicationpath
argument, similar to the way this argument is used in the command for El Capitan.
After creating the bootable installer, follow these steps to use it:
