On Lenovo N22 80S6 Ubuntu doesn't show on the boot menu after I "successfully installed" it. Here is the step-by-step of what I did:
(1)Downloaded Ubuntu 16.04.1 ISO, used YUMI to burn it to my 1TB seagate portable drive.
(2)Changed boot mode to Legacy Support and boot priority to Legacy First because I read that somewhere.
(3) Installed Ubuntu without trying live because on live, the installer got stuck on downloading package.
(4) I did not select "something else" but this is what that screen looks like. I'm only showing this because I feel like something's not right there.
(5) Then I got this message.
(6) After 10-15 min the installation was supposedly finished.
(7) Unplugged the USB and computer shut off. When I turned it on I got a boot menu with 2 choices: eMMC Disk Samsung 64GB and Windows Boot Manager. Hitting enter on either of those choices just brought me back to the boot menu. I no longer have Windows (that was my decision but now I wish I had saved it so I can give up on Ubuntu).
boot-info
script, this may useful investigating your problem further. You can also try this answer from the live media: askubuntu.com/a/88432/40581 Save the error messages that may be generated. I assume eMMC isn't what the Ubuntu installer expects which causes some issues or your device is trying to boot in UEFI mode and just can find any EFI boot image (or a mix of both), in this case you should install Ubuntu in UEFI mode if possible.
