Create a Portable Linux System on a USB with Persistence (Advanced Live USB)

Instead of a normal live USB, create one that saves files, settings, and installed apps.

What You’ll Need:

A USB (16GB+ recommended)

ISO of a distro like Ubuntu or Fedora

Rufus (Windows) or dd (Linux)

Steps (Linux Method):

sudo fdisk -l # Find your USB
sudo dd if=ubuntu.iso of=/dev/sdX bs=4M status=progress

Then:

Create a second partition on the USB.

Format it as ext4.

Label it casper-rw.

Now your Linux USB remembers everything — apps, WiFi passwords, files.
Perfect for ethical hacking labs, testing environments, or portable dev setups.
