Unable to dual boot Ubuntu 15.04

You did not say what the other dual boot OS is, so I picked Windows 8.1. There is some way to dual boot 15.04, many have done it. My first thought, have you checked download with MD5sum or SHA256sum? The download may have missed the section you need. Check sites below for information about dual booting Ubuntu 15.04

    Thanks for your response, Michael. I wish to dual boot Ubuntu 15.04
    with 14.04. Dual boot has been an option in the past, but not so
    with 15.04, which leaves me disappointed and annoyed. Is there a
    reason for this, and can this be bypassed?

How did you initiate the Ubuntu install? What steps did you take?

        Hi AP. I took the usual steps through the Install Menu, only
        to find there is no option to install Ubuntu 15.04 as part of a
        dual-boot system with Ubuntu 14.04, unlike previous releases
        i.e. Ubuntu 12.04 installed alongside Ubuntu 14.04. But this
        option has been removed in 15.04 - WHY?

People dual boot quite happily.

What I can suggest is that you remove the current Ubuntu partitions and reinstate the Windows boot loader so that Windows boots on it's own. You can then boot to the 15.04 install media and install to the freed space.

You do realise that 14.04 is only supported until July next year wheras 14.04 is supported til April 2019....

Why upgrade at all?

      Have you misunderstood my problem - what's with the Windows stuff?
    I wish to dual boot UBUNTU 15.04 with UBUNTU 14.O4 already
    installed, but THERE IS NO PROVISION FOR THIS IN THE UBUNTU 15.04
    INSTALL MENU, unlike previous releases. So I am still in the dark as
    to how this can be accomplished - but thanks again for your response.

What selection options do you see on the 'Installation type' screen http://www.linuxbsdos.com/wp-content/uploads/2012/05/PartitionOptions-600x379.png ?

I am quite sure that you can use the 'something else' selection to install a second Ubuntu version I parallel to another one that is already installed.

    Thanks for your response, Manfred. The 15.04 installation disk has
    the usual options, minus "install Ubuntu alongside", so yes: I do
    have "something else", but I've no experience with partitions
    management. And I'm still puzzled by this 'non improvement' to the
    installation process, wondering what prompted Ubuntu to remove the
    option that made this process a simple click for the user.

How much RAM do you have?

You could alwys install 14.04 and then in April next year, upgrade directly to 16.04 (LTS to LTS upgrades are supported).

    I have 6MB of RAM, but thanks for suggesting I wait for 16.04 -
    hadn't realised it would be coming so soon. I've had endless
    problems since installing 14.04, usually immediately after
    installing an update, and am wondering if it's just not working well
    with my Acer E1-531.

    Thanks again for your advice.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.
