Introduction

Userful™ software appliance can be installed from a USB flash drive (USB keys, thumb drives, etc). Booting from USB flash drive will behave just as if booted from the install CD.

This document provides instructions on how to create bootable USB drive on the Linux operating system. For Windows, you can download any tool (e.g. Win32 Disk Imager) from online sources and follow the instructions.


Steps to create a bootable USB flash drive from an ISO image

  1. Login to the Linux Desktop session and open terminal
  2. Plug in the USB key (4GB or more)
  3. Type in the following command, to identify the USB key
  4.  $ dmesg

    The output will look something like:

    sd 6:0:0:0: [sdx] Attached SCSI removable disk
    where sdx represents the USB key name


  5. Type in the following command, replacing "path/to/file" with the path to the .ISO file and "/dev/sdx" with path to USB key. Enter the "user_account" password when prompted.
  6. $ sudo dd bs=8192 if="path/to/file" of="/dev/sdx"


    Please Note: Make sure that the USB flash drive you are using is not mounted. dd command erases the content of the USB flash drive and does not have any progress bar.

  7. After completion, open the USB flash drive to view the content
  8. Close the folder and right-click on the drive's icon and click "eject". Wait one or two seconds -- or until indicator lights on the device stop flashing -- and remove the device. (This last step is critical in preventing data loss or damage to your storage device)

Note:

  • To install the product, simply plugin the USB key and configure the system to boot from the USB.
  • Ensure that you disable UEFI Boot Order while you are in the BIOS of the system. Go to Advanced > Boot Options and Disable UEFI Boot Order (HP EliteDesk 800 G2 Series system is considered as an example to quote the steps). Different computers have different BIOS and therefore this step is a guidelines only.
  • Save the settings and reboot the system and follow the Installation prompts.
