Cannot boot from Thin Client OS USB

HP Recommended
Thin Client T420

Hi all,


I was wondering whether you could help. Basically I want to revert a T420 back to Thin Client OS 6.1.0 from Thin Client OS 7.0.0 but the USB boot does not kick in before the OS boots. I have copied the image from another T420 as well as creating the image using the HP Thin Client Image Tool for Windows but no joy either way. Is there anything else you can suggest to accomplish this task? Your help would be much appreciated.


Kind regards,
