Download Rufus from RUFUS.ie, a utility that easily creates bootable media for both MBR and GPT partitions.
- Open Rufus and select the device (USB) you want to make bootable.
- Choose the GPT partition scheme for UEFI. Leave the File System & Cluster Size at their default settings, and name your drive.
- Tick ‘Create a bootable disk using’, ensuring that the ‘ISO Image‘ option is selected from the dropdown menu. Click on the drive icon next to the dropdown to locate and select your ISO file.
- Click “Start” and wait for Rufus to complete the process of writing the ISO to your USB flash drive.
