I have windows 10 on my machine and I decided to install Ubuntu 16 alongside it.

After the installation process there is no GRUB and I cannot launch Ubuntu. I tried to launch it by manually choosing Ubuntu from boot devices but it says boot device not found.

I turned off fast boot and tried to install again. It did not work. I tried to turn on legacy boot and install again. This did not work either. I tried to put recovery USB drive of Windows 10 and install Ubuntu again. This failed as well.

I tried to repair MBR through command prompt. All the operations were successful but I still cannot launch Ubuntu. I am stuck now and do not know what to do.

Your boot flag must be set set to the wrong partition.

Same happened with me when I dual boot ubuntu and windows but couldn't load any.

So, try checking the partitions using any partition editor.

Since none of your OS is loading up, you should boot using GParted live usb.

Then in partition manager, check for the boot flag.

It must be set to the partition where the /root is installed.
