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 bootable USB.

1️⃣Stage 1. Format USB as FAT32

Creating a bootable USB drive has specific file system format requirements; the USB flash drive must be set to FAT32 format first. However, Disk Management and CMD can't format a USB larger than 32 GB to FAT32. You need to turn to a third-party format tool. Our tests verify that EaseUS Partition Master is a stable formatting utility. It can format 64/128/256 GB USB to FAT32. Download this tool and follow the guide below to try it.

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.

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