Download the Best USB Bootable Software

EaseUS Todo Backup is recommended here as the best USB bootable software, plus an essential bootable USB creation tool for personal users and companies. It's all-in-one software that integrates both bootable USB and ISO image together, which facilitates users to create portable Windows 7/8/10 that greatly reduce worry in case of an unexpected system failure, crash and similar disasters that cause a complete shutdown.

With EaseUS Windows backup software, customers can gain the following benefits:

Two Ways to Create a Bootable USB

With the help of the EaseUS Windows backup software, you are able to create a bootable USB drive in two ways.

• Easily create a portable Windows USB that contains system and user files.
• Simply create a WinPE-based bootable USB stick that can only boot into EaseUS Todo Backup.

Follow the step-by-step guide below, and make your own bootable USB drive with the amazing bootable USB creator.

First and Foremost - Create a Portable Windows USB Disk

Creating a portable USB is your very first choice. All you need to do is download the useful system cloning tool and clone the operating system to your portable device.

During the system cloning process, you can create a portable USB drive. You can boot Windows from the USB drive anytime if you're trying to restore a crashed system even the computer did not install EaseUS Todo Backup software.

Step 1. Launch EaseUS Todo Backup. Expand the menu and click 'System Clone' in the lower position.

Step 2. On the 'System clone' window, the software will choose the system partition and boot partition by default. Just Choose the USB drive as the destination disk.

Click on 'Advanced options' and then 'Create Portable Windows USB drive'. Click 'OK'.

Click 'Proceed'. The software will start immediately cloning the default partitions of your desktop/laptop to the USB drive. After the cloning process is over, you can safely plug the USB drive out.

Step 3. To boot the cloned system from the USB drive on other Windows devices, just connect the drive to the device. After the connection, wait for the computer configuring system settings and you will finally arrive at the desktop screen that's exactly the same with that of the cloned system.

Put the 'username' and 'password' of the cloned system. You should now successfully enter the cloned system.

Guide - Create a WinPE-Based USB Disk

If you don't want to clone your system to the external device, just want to export the data on the computer, you are advised to create an emergency disk with EaseUS Todo Backup.

By this means, you are only allowed to boot into EaseUS Todo Backup even when your computer or laptop cannot boot as usual. Once you boot into this backup software, you can back up data to an external device or copy files without Windows. Let's see how to create this WinPE disk.

1. Prepare a USB drive which can be written and read.

2. Launch and install EaseUS Todo Backup on the Computer B

3. Open the tool and click Tools - Create Emergency Disk.

4. Select 'Create WinPE emergency disk'.

5. Select a bootable media type: here we choose USB drive.

6. Click Proceed to create a bootable disk.

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.

Download macOS

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.

Use the 'createinstallmedia' command in Terminal

1. Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.
   Catalina:*
   Mojave:*
   
   High Sierra:*
   El Capitan:
   
4. Press Return after typing the command.
5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
7. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

* 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.

Use the bootable installer

After creating the bootable installer, follow these steps to use it:

1. Plug the bootable installer into a compatible Mac.
2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
   Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
3. Choose your language, if prompted.
4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
