Hello. I just acquired an Insignia Flex 11.6 running Windows 10, and would like to turn it into a dual-boot machine running the existing Windows OS, as well as Ubuntu Linux.
However, I have not found a way to get it to boot from the USB drive that contains Ubuntu Linux and the installer. I have successfully gotten to the Aptio setup utility, disabled the secure boot, the quiet boot and the fast boot, as well as tried the boot override.
In all cases, the computer ignores the USB drive and boots into Windows. I'm sure the USB drive is bootable, since it works on other machines.
