Creating a Bootable USB Flash Drive with Microsoft Windows

Use the Fedora Media Writer app on a Windows system to create a bootable USB flash drive that you can use to install JSA software.

You must have access to an 8 GB or larger USB flash drive.

1. On your Windows system, download and install the Fedora Media Writer app from the Fedora Media Writer GitHub repository.

   Other media creation tools might work to create the bootable flash drive, but the JSA ISO is a modified Red Hat ISO, and Red Hat suggests Fedora Media Writer. For more information, see Making Installation USB Media.

2. On your Windows system, download the JSA ISO image file from https://support.juniper.net/support/downloads/ to a local drive.
3. Insert the USB flash drive into a USB port on your Windows system.Note

   Any files stored on the USB flash drive are overwritten when creating the bootable flash drive.

4. Open Fedora Media Writer and in the main window, click Custom Image.
5. Browse to where you downloaded the JSA ISO on your Windows system and select it.
6. Select the USB flash drive from the Fedora Media Writer menu, and then click Write to disk.
7. When the writing process is complete, click Close and remove the USB flash drive from your system. For more information about installing JSA software, see Installing JSA with a USB Flash Drive.

Installing JSA with a USB Flash Drive

Follow this procedure to install JSA from a bootable USB flash drive.

You must create the bootable USB flash drive before you can use it to install JSA software.

This procedure provides general guidance on how to use a bootable USB flash drive to install JSA software.

The complete installation process is documented in the product Installation Guide.

1. Install all necessary hardware.
2. Choose one of the following options:

   • Connect a notebook to the serial port at the back of the appliance.

   • Connect a keyboard and monitor to their respective ports.

3. Insert the bootable USB flash drive into the USB port of your appliance.
4. Restart the appliance.

   Most appliances can boot from a USB flash drive by default. If you are installing JSA software on your own hardware (only supported for Data Nodes), you might have to set the device boot order to prioritize USB.

   After the appliance starts, the USB flash drive prepares the appliance for installation. This process can take up to an hour to complete.

5. When the login prompt is displayed, type root to log in to the system as the root user.

   The user name is case-sensitive.

6. Press Enter and follow the prompts to install JSA.

   The complete installation process is documented in the product Installation Guide.
