I installed Ubuntu 16.04 with dual boot. Dual boot with Windows 10 seemed to work well. Then I immediately upgraded to Ubuntu 17.04, and I could successfully boot into Ubuntu. However from the first time I decided to reboot from Windows 10, the dual boot menu no longer shows up at startup.

I now started Ubuntu from the USB "Try Ubuntu". I installed boot-repair and you can find the diagnostic here. I haven't actually tried to repair yet, I would like to have some expert advice before proceeding. Thanks!

I'm not sure if this will work for you, but it worked for me when I had the same issue.

First, go to your BIOS settings, and go to System Configuration. From there, select Boot Options.

Under Boot Options, you should have a list called UEFI boot order or boot sequence or something similar. The first option in that list will probably be OS Boot Manager. Highlight that option using your arrow keys, and press Enter.

If I'm right, a dialog box like thing will pop up, and it'll display two options. Windows Boot Manager as the first option, and Ubuntu as the second. Press F5 to move Windows Boot Manager to the bottom, below Ubuntu, and then press F10, and then F10 again to save and exit.

After all these steps, your system will reboot, and hopefully, the GRUB menu should appear again. :)
