Downloaded the Ubuntu 16.04.2
.iso install disk and flashed it onto a USB stick.
Booting on the USB stick, there is no memtest86+ option (along with "Try Ubuntu").
Is there a way to add it to the install options?
(it's for a UEFI boot PC running normally Windows, its owner does not want to install Ubuntu. "memtest86+" is completely free (unlike "memtest86"), but is quite old, and does not offer a UEFI boot - this is why having it within the Ubuntu options makes things easier)
