Use Rufus to write an .iso file
- Download Rufus . Rufus is a standalone program and does not require installation.
- Open the Rufus program from where you downloaded it to run it.
- From the Device drop-down menu, select your USB drive, if it isn't automatically selected.
- Under "Boot selection", select Disk or ISO image (Please select), if it isn't already chosen, and then click SELECT to choose the .iso file you downloaded.
- Leave "Image option" set to Standard Windows installation.
- Leave "Partition scheme" set to GPT.
- For "Target system", select UEFI (non CSM).
- Under "Format Options", to ensure the flash drive is compatible with UEFI, select FAT32 for "File System".
- To create the flash drive with the "Press any key to boot from USB" prompt at startup, under the "Advanced format" options, select Create extended label and icon files.
- When you are finished selecting options, click Start. When prompted, confirm that you want to erase the flash disk.
- The .iso files will start copying to the flash drive; the process can take several minutes. When Rufus is done, close the program and eject and remove the flash drive.
