Create a Bootable Pop!_OS USB in Linux

This section explains the process of creating a bootable Pop!_OS USB in Linux using Popsicle.

Install Popsicle

Popsicle is a Linux utility for flashing multiple USB devices at once. You can install Popsicle as an AppImage or a Flatpak.

Download the Popsicle AppImage from this Popsicle repository.
Navigate to the downloaded AppImage. Right-click the AppImage and select Properties.
Select the Permissions tab and check the Execute box.
Double click the Popsicle AppImage to launch it.

Follow the instructions on Flatpak.org if Flatpak is not installed in your Linux distribution.

Open a Terminal session and enter this command:

flatpak install flathub com.system76.Popsicle

Enter this command to launch Popsicle:
```
flatpak run com.system76.Popsicle
```

Linux Download ISO

Download the appropriate Pop!_OS.iso file for your target system. See the preparation guide for information about each version.

Take note of the hash value for your chosen ISO. Use this value to verify the integrity of the ISO file in step four of the installation process.

Compare Hash Values

Flash your USB media with the Pop!_OS.iso image. Note that this process will completely erase all previous data on the USB storage device.

Launch Popsicle. The app may display as USB Flasher in search results.
Click Choose Image.
Navigate to the local directory with your Pop!_OS.iso file and select it.
Click the drop down menu next to Hash and choose SHA256, then click Check. Compare the hash result to the value you saw when selecting your Pop!_OS.iso file.
Click Next.
Select the USB installation media. Click Next.
Enter your system password if prompted, then wait for the installation to complete.
Click Done when the process completes.
