    So, tell us about those installations (same or different disks) and if you installed GRUB2 and where.

    Try going into your bios and put Ubuntu as your first boot drive.

    When you install Ubuntu alongside other operating system e.g. windows the GRUB (Grand Unified Boot Loader) is automatically installed and configured. In your case it seems either the GRUB was not installed or is broken. You need to first boot into Ubuntu and check if grub is correctly installed and configured.

    To boot ubuntu you can do the following:
    While the system is booting and still showing the logo hold down the shift key on the keyboard (sometimes this doesn't work and you need to hold down SPACE or ESC). This will show the GRUB menu select Ubuntu and press enter.

    If the above doen't work and if you couldn't get a GRUB menu then that could mean a broken GRUB and you might need to reinstall GRUB following the steps given here.

    If the above works and you get the GRUB menu then sometimes just updating grub fixes the problem. Updating the grub is very simple. Type the following command in your terminal and execute.

    "sudo update-grub"

    The above command will regenerate the /boot/grub/grub.cfg file based on the files contained in /etc/grub.d and the configurations saved in the file /etc/default/grub

    I hope this helps
