    UEFI settings after reboot -> Boot Options -> BBS Priorities. From there, on some UEFI machines, you can setup what OS should be loaded by default

    I have downloaded ubuntu-16.04-desktop-amd64.iso and created a bootable disc which works fine. I have also created a 50,000 MB partition on my laptop hard drive.

    When I run the ubuntu install, I do NOT get the option “Install ubuntu alongside Windows Boot Manager

    Also, when I choose “something else” my new partition comes up as “unusable“. Any suggestions?

    • Roger Boisjoli says:

      OK. Figured it out. When I created my partition, I ended up with five partitions. Deleted one which was used for installing MS Word. Never intend on using it so no loss. Ubuntu installed perfectly.

    • Matei Cezar says:

      50 MB is to small to install Ubuntu. use a large partition.

    I installed Ubuntu 16.10 on windows 7 on laptop Dell 5537 i5. Ubuntu was working fine. But I couldn’t boot to win7? Before that, I installed Ubuntu 14.10 then both Ubuntu 14.10 and win7 were working fine. Are there somethings wrong?

    I followed this instruction for installing Ubuntu 14.04 alongside windows 7 and it destroyed the windows completely and installed ubuntu utilizing entire HDD space. I think the same is reported by some other people… Please verify this..

    Creation of Root partition : it is mentioned that the size should be at least 20000MB. But the screen shot shows 10914 MB. When I press + I get error message ‘No root file system is defined

    How to proceed?

    I have had recent success with the UEFI install of Ubuntu 16.04. Having downloaded the correct version of the Ubuntu iso image file, you should also download the Rufus disk imager, available at, and browse to your Ubuntu image, with the settings shown in the screenshot on the provided on the above link.

    Allow the program to image your removable drive. Once complete, open windows disk management and shrink the C: volume by at least 20gb and leave this unformatted.

    Once complete, reboot your computer and boot to the removable drive, (where if in your boot options menu you have two options you should choose the UEFI option). In the GRUB 2 bootloader, choose ‘Install Ubuntu‘. Follow the installer until you reach the install options page, where you should choose ‘Something else‘.

    You need to then find your empty partition and create a swap partition by making a 2gb partition formatted as ‘Linux SWAP‘. Following that, you should then in the remaining space, create an ext4 formatted partition for your install of Ubuntu, selecting the mount point in the drop menu as '/'.

    Once you have done this, you need to select the location for the install of the GRUB bootloader. This should be installed to the partition labeled ‘Windows Boot Manager : UEFI‘. Note that this WILL NOT destroy your windows boot manager, but install GRUB 2 alongside it, allowing GRUB 2 to see the windows bootloader. You should then proceed with the install.

    Once the install has finished, reboot and remove your removable drive and enter your BIOS boot order settings. You should move Ubuntu above windows in the OS boot section. Save, exit and reboot and you should see the GRUB 2 bootloader with he option for both Ubuntu and Windows Boot Manager.
