How To create a bootable USB using Rufus, follow these steps:
Download and install Rufus on your computer.
Insert the USB drive you want to make bootable.
Open Rufus and select the USB drive from the Device dropdown menu.
Choose the ISO image or other bootable file you want to use from the Boot Selection section.
Adjust the partition scheme and target system type to match your computer's configuration.
Click the Start button to begin the process. Rufus will format the USB drive and copy the bootable file to it.
Wait for the process to complete. Once it's finished, you'll see a message indicating that the bootable USB drive has been created successfully.
Eject the USB drive and use it to boot your computer from the USB drive.
Remember that creating a bootable USB drive will erase all data on the USB drive, so make sure to back up any important files before proceeding.
