A bootable USB drive is an external storage device that contains an operating system, allowing a computer or laptop to boot from it. Many users create a bootable USB drive in Windows for three main purposes. In this post, we’ll show how to make different bootable flash drive in Windows 11.
Preparation: Choose a suitable USB and format it
To make bootable flash drive Windows 11, you need a USB drive with at least 13 GB of storage. A USB 3.0 drive is recommended due to its faster read and write speeds, ensuring a smoother installation process. Since all data on the USB will be erased, it’s essential to back up any important files beforehand.
When formatting the USB, make sure it is set to FAT32 and uses the GPT partition style, as these settings are required for UEFI booting. However, Windows' built-in tools like Disk Management and Command Prompt cannot format USB drives larger than 32 GB to FAT32. In such cases, using a third-party tool like AOMEI Partition Assistant is a reliable solution. This utility allows formatting of USB drives up to 64 GB, 128 GB, or even 256 GB to FAT32 without compatibility issues.
