    Newly installed Kubuntu boots to Windows instead

    I just finished installing Kubuntu 12.04.1 on my laptop, which already had Windows 7 installed. The Windows boot partition is sda1; the Kubuntu boot partition is (or is supposed to be) sda6. The installation had a couple of minor burps that I didn't worry about. But now, when I reboot, I get into Windows rather than Kubuntu. I was expecting to see the Grub2 screen, offering me a choice of systems to boot to. I think I can get into Kubuntu by booting into SuperGrub, but I shouldn't have to. What might have gone wrong?

    Is this a newer machine? You say that /dev/sda1 is the "Windows boot partition;" does that mean that there is a separate small partition for booting at the front of the drive? I'm asking because I'm wondering if your problem is (U)EFI-related. This is a typical symptom of such cases.

    It's a new machine

    Yes, it's a new machine -- a Lenevo Z580. It came with 4 primary partitions, so I had to go through some gyrations to make a partition available for Linux. Right now the configuration is:

    sda1 Windows boot
    sda2 Windows C:
    sda3 Extended
    sda4 Windows recovery (I think)
    sda5 Windows D:
    sda6 Kubuntu /
    sda7 Kubuntu /home
    sda8 Linux swap

    I don't know anything about (U)EFI -- that's not the kind of information that laptop makers provide to buyers.

    Now I'm wondering -- am I going to wreck something if I install Grub using grub-install?

    pwabrahams; Hi !

    It does appear that sda1 (as stated windows boot ) is UEFI, and that does present a problem, that is surmountable, to install grub properly. A bit more effort on your part.

    Here are the relevant links with background info to resolve:

    To verify UEFI:
    You can find out by typing "bcdedit" in a Windows Administrator Command Prompt window and looking for the "path" line in the "Windows Boot Loader" section. If this line refers to winload.efi, then you're booted in EFI mode; if it refers to winload.exe, then you've booted in BIOS mode.

    Kubuntu, not Ubuntu

    The instructions at https://help.ubuntu.com/community/UEFIBooting are for Ubuntu, not Kubuntu. They involve a "boot repair" step that doesn't seem to exist (or at least I can't find it) after the reboot of Kubuntu.

    Re: Kubuntu, not Ubuntu

    If I understand it correctly, you can install (temporarily) bootrepair while using the liveCD.

    If you have used a liveUSB with persistence, it can be permanently installed on the liveUSB.
    If you don't make backups of your important data, your data is obviously not important to you.
