Using MDT 2012 to create Media (ISO) to then transfer to bootable USB and deploy image.
USB Drive: Kingston Datatraveller 111 (3.0)
System: HP ProBook 4330s, 4340s
BIOS Booting configured to use Legacy Mode with Security Mode disabled - I believe this is required in order to boot from USB instead of using UEFI.
Deployment of image seems to get through part of Task Sequence, but at some stage (varying) we get a Windows Dialog stating "Media Not Found. Please reinsert the media (CD, DVD, or USB) needed to complete the deployment." at which point the USB drive appears to be totally unrecognised. At this point if I insert into another Windows device, we get a "You need to format the disk in drive E: before you can use it.".
I can place another (different model USB) into stalled deployment and it completes.
