Media Manager help

[WirSysPlus]

Client wanted more advanced recording. Told him about Media Manager. He bought a NUC from Dell with Linux Ubuntu(?) pre-installed.
I downloaded both the application server software and the Avaya USB creator, made the USB and went to the client site to install.
After an hour screwing around with the Dell SecureBios crud, I finally was able to boot from the USB. System didn't install. A message indicating a file error was displayed.
Tried a different USB, same issue.
Anyone know what I need to do?

Which Dell model are you using and which Application Server release are you trying to load?

Optiplex 7011 (? don't remember off the top of my head).
App server abe-11.0.4800-17_e16.iso (matches the client IPO).
