The
HP Vision Diagnostics ISO can be added to an E2B
Removable USB drive if you use the .
ISOPE01 file extension. It will boot straight to WinPE and you should briefly see the blue console shell window which will load the ISO as a virtual drive and allow it to find the drivers and diagnostic programs inside the ISO.
If you have a E2B
HDD, you will need to convert the ISO to a FAT32 .imgPTN file (or if you boot it as .isoPE01, you could use the SHIFT+F10 key and run \_ISO\e2b\firadisk\LoadISONP.cmd from the E2B USB drive to load the ISO file as a virtual DVD to allow the diagnostic files to be seen).
The HP PC Hardware Diagnostics 3-in-1 USB Key software however, does not come as an ISO file.
Here is how to add it (or the Vision Diagnostics ISO) to E2B.
