Now, let's start learning how to boot from a USB on Windows 11. In this article, we divide the whole process into three stages. First, make your USB well-prepared for the ISO file.

1️⃣Stage 1. Format USB as FAT32

Burning the Windows 11 ISO file to a USB flash drive has specific file system format requirements; the USB flash drive must be set to FAT32 format first. If your USB is FAT32 formatted, skip to the next stage. If not, follow the steps below to format the USB as FAT32:

Step 1. Connect a USB drive with 32GB or more storage capacity to your laptop or desktop. (Remember to back up your important files in advance to avoid data loss.)

Step 2. Press Windows + I keys to open File Explorer; right-click on your USB drive.

Step 3. Select "Format," select FAT32 as the file format, and click "Start." Then wait patiently.

2️⃣Stage 2. Burn Windows 11 ISO File to USB

Because Windows 11 does not have a built-in easy-to-use ISO file-burning tool, we need to choose trustworthy third-party software. After many tests, we decided to recommend EaseUS Partition Master to you. This tool can directly burn the Windows 11 and 10 ISO files to the corresponding USB for you. And in our many tests, this tool has successfully completed the task. So download it and follow the tutorial below to get started.

3️⃣Stage 3. How to Boot From USB on Windows 11 - 2 Cases

When you need to boot from USB on Windows 11, you may encounter two main situations. One situation is that your computer is working fine, and you can access the startup disk settings from the Windows Settings app portal. The other is when your computer goes wrong and crashes and doesn't work properly, at which point you need to access the boot menu and boot your computer from USB in the BIOS. Now let's learn about each method.

Case 1. PC Can Start Properly - From Settings

Windows Settings can help you start from a USB; follow the given tutorial below to boot Windows 11 from USB while your computer still runs smoothly.

Step 1. Insert the USB flash drive you just burned the ISO file into your Windows 11 computer. Press Windows + I to open Settings, and select the "System" > "Recovery" option.

Step 2. Click the Restart Now button to the right of Advanced Startup. In the popup window, Windows 11 will let you know that it's going to restart your device and that you'd better save your work until then.

Step 3. Afterward, your PC will restart and load into the recovery environment. Under the Choose an option window, select the Use a device option.

Step 4. Your PC will list the bootable devices your computer can use, including the USB drive you connected to your PC earlier. Click and select it.

Finally, your computer can reboot and boot from the USB drive you set up.

Case 2. PC Fails to Start - From Boot Menu

When your computer doesn't boot, you need to access BIOS to boot Windows 11 from USB. Here's how:

Step 1. Connect a bootable USB flash drive to the USB port of a PC. Press the power button to start the laptop or PC. When it starts to load, go ahead and hit the appropriate boot menu option key, such as ESC, F2, F8, or F10 (it may vary by brand), to enter the BIOS setup.

Step 2. In the boot menu, look for Boot order and move the USB drive you want to boot to the top of the list.

Step 3. After confirming the settings, press F10 to save and exit. After exiting, your PC will boot from the USB flash drive.
