Verifying an installed image

Once an image has been installed and configured, you can verify the hash against what was built and signed during the Trusted Build process. To perform this verification, you will need the vx-iso USB drive and the hash of the image.

First, be sure the system is powered off. The simplest way to do this if the machine is running is by pressing the power button.

Once the machine is powered off, insert the vx-iso USB drive.

Power the system back on and be ready to interrupt the boot process. On vxadmin and vxcentralscan laptops, this should be the F12 key. On vxscan, you will need to use the Del key.

For vxadmin and vxcentralscan, once you are in the Boot Menu, select the USB drive and press Enter.

For vxscan, once you are in the BIOS (you may need to enter the BIOS password), navigate to the Boot menu option, then select the USB drive to boot from.

After booting to the USB drive on any of the systems, you will be booted into a minimal menu. Using the arrow keys, navigate to the Verify Hash option and press Enter.

This will automatically calculate the hash of the installed image, and you can then compare it with the hash created during the Trusted Build process.

Once you have verified the hash, you can press Enter to reboot. Be sure to remove the vx-iso USB drive as well.
