    Question Dual boot does not show up when I boot my laptop


    Hello everyone!
    I have been using Ubuntu 12.10 for a few weeks then two days ago I decided to install on the same machine Linux Mint 13 Cinnamon.

    Problem is: when I switch on the laptop, no dual boot is present. It just goes into Mint, like it was the only Os on my computer.

    So... how do I fix this little problem?

    Boot up Linux Mint and execute these commands in Terminal :
    Code:
    df -h
    sudo fdisk -l
    Post output here.

    It looks like something went wrong with installation.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Okay, this is weird: I had to reboot the pc after installing Steam and... I had the dual boot thing! I did not do anything installing Steam aside (and I don't think that that was the solution!). So I thought maybe it works only if you reboot. I switched off the computer, then switched on again and I had the dual boot thing also with switching on. I am sorry I cannot help anyone with a similar problem: mine apparently fixed itself...

    Alrighty ! Problem solved itself... There must be some explanation for this. One thing is confusing me. In which distro did you execute fdisk -l command? Ubuntu or Mint?

    Mint because the pc started only on Mint. Yeah, I wish I know how it fixed itself. I mean, I am happy, right?, but to not know something is just annoying

    According to output of df -h command, Mint has been installed in last partition, /dev/sda6 and Ubuntu has been installed in first partition, /dev/sda1.

    Which distro's GRUB Menu appear at startup?

    What do you mean? (okay, I am a newbie) You mean which distro is the first 'choice' in the grub menu? It's Mint

    Here is what I see when I am on the screen to choose OS

    Linux Mint, with Linux 3.2.0-23-generic
    Linux Mint, with Linux 3.2.0-23-generic (recovery mode)
    Memory test (memtest86+)
    Memory test (memtest86+, serial console 115200)
    Ubuntu --class ubuntu-- class gnu-linux -- class gnu-- class os
    (then the two lines of Ubuntu - ubuntu and ubuntu recovery mode)
