How to Install Grub on a USB Flash Drive for Mac

If you want to boot Ubuntu or another Linux distribution from a USB flash drive on your Mac, you need to install a boot loader called Grub on the drive. Grub is a program that lets you choose which operating system to load when you turn on your computer. In this article, we will show you how to install Grub on a USB flash drive for Mac using a simple method.

What You Need

A USB flash drive with at least 4 GB of free space

A Mac computer with an internet connection

A Ubuntu ISO file downloaded from https://ubuntu.com/download

A software called Etcher that can write the ISO file to the USB drive. You can download it from https://www.balena.io/etcher/

Step 1: Prepare the USB Stick

Before you install Grub on the USB stick, you need to format it as FAT32. This is a file system that is compatible with both Mac and Linux. To format the USB stick, follow these steps:

Insert the USB stick into your Mac and open Disk Utility from the Applications folder.

Select the USB stick from the left sidebar and click Erase.

Choose MS-DOS (FAT) as the format and give it a name. Click Erase again and confirm.

Wait for the process to finish and then eject the USB stick.

Step 2: Install and Run Etcher

Etcher is a software that can write the Ubuntu ISO file to the USB stick and make it bootable. To install and run Etcher, follow these steps:

Download Etcher from https://www.balena.io/etcher/ and open the dmg file.

Drag and drop the Etcher icon to the Applications folder.

Launch Etcher from the Applications folder and grant it permission to access your files.

Step 3: Etcher Configuration

Etcher has a simple interface that lets you select the ISO file and the USB drive. To configure Etcher, follow these steps:

Click Select Image and choose the Ubuntu ISO file that you downloaded earlier.

Click Select Target and choose the USB stick that you formatted earlier.

Click Flash and enter your password if prompted.

Step 4: Write to Device

Etcher will start writing the ISO file to the USB stick and install Grub on it automatically. This may take some time depending on the speed of your USB stick and your computer. To write to device, follow these steps:

Wait for Etcher to finish flashing the USB stick. You will see a progress bar and a percentage indicator.

When Etcher is done, it will verify the data on the USB stick and notify you if everything is OK.

Eject the USB stick safely from your Mac and remove it.

Step 5: Boot Your Mac

You have successfully installed Grub on a USB flash drive for Mac. Now you can boot your Mac from it and try Ubuntu or another Linux distribution. To boot your Mac, follow these steps:

Insert the USB stick into your Mac and turn it on or restart it.

Hold down the Option (Alt) key until you see a list of bootable devices.

Select EFI Boot or Windows (depending on how your USB stick is labeled) and press Enter.

You will see the Grub menu with a list of options. Choose Try Ubuntu without installing or Install Ubuntu depending on what you want to do.
