Once Disk Utility is open, select the USB drive from the list of devices on the left-hand side. Click on the Erase tab at the top of the window. In the Format dropdown menu, choose either MS-DOS (FAT) for FAT32 or exFAT depending on your preference and the size of the USB drive. FAT32 is compatible with older systems but has a file size limit of 4GB, while exFAT supports larger files and drives. Name the USB drive something memorable, such as "BOOTCAMP," and click Erase to begin the formatting process. This will take a few moments, after which the USB drive will be ready for the next steps in creating a Boot Camp installer.

After formatting, verify that the USB drive is correctly formatted by checking its properties. Eject the USB drive from your Mac and reconnect it to ensure the system recognizes it properly. Open Disk Utility again, select the USB drive, and confirm that the format is displayed as either FAT32 or exFAT under the Format section. Additionally, check the Partition Map Scheme; it should be set to Master Boot Record (MBR) for compatibility with Boot Camp. If the partition map is incorrect, you may need to erase the drive again and ensure the correct scheme is selected during the formatting process.

With the USB drive properly formatted, it is now ready to receive the Windows ISO file for Boot Camp installation. Ensure the USB drive has sufficient space to accommodate the Windows ISO and any additional files required by Boot Camp Assistant. A 16GB or larger USB drive is recommended to avoid running out of space. Keep the USB drive connected to your Mac, as the next steps will involve using Boot Camp Assistant to download the Windows support software and create the bootable installer.
