iso2usb

A simple Bash script for writing Linux ISO files to a USB drive using dd.

Features

• Automatically detects connected USB drives
• If multiple drives are found, prompts the user to select one
• Checks that the USB drive is large enough to fit the ISO
• Automatically unmounts any mounted partitions on the target drive
• Displays write progress in real time

Requirements

• Linux
• bash, dd, lsblk (included in most distributions)
• Root privileges

Installation

git clone https://github.com/yourusername/iso2usb.git
cd iso2usb
chmod +x iso2usb

Optionally, install it system-wide:

sudo cp iso2usb /usr/local/bin/

Usage

sudo ./iso2usb <iso-file>

Example:

sudo ./iso2usb ubuntu-24.04-desktop-amd64.iso

Notes

• Linux ISO files only. Windows ISOs are not supported – use Ventoy or WoeUSB for those.
• All data on the selected USB drive will be permanently erased.
• You must type YES (uppercase) to confirm before anything is written.
