    No choice of OS on boot. Dual booting W7 and Xubuntu

    I've installed Xubuntu alongside Windows 7, but when booting, it just goes straight into Windows. Did GRUB just not install or something ?

    If it matters, I'm using an ASUS K55VD Laptop.I think​ it has UEFI, but I could be wrong.

    I think it is ok as General question.

    But if UEFI, did you install Xubuntu in UEFI or BIOS/CSM mode? Did you install with 64bit version?

    Post the link to the BootInfo report that this creates. Is part of Boot-Repair:

    Ok, so I asked in the IRC channel, and it was determined I do have UEFI enabled. I don't think I installed it in UEFI mode, but it never asked :/

    Here's the output of bootrepair: http://paste.ubuntu.com/5681014/

    What should I do?

    Did you install the 32 bit version. That does not have UEFI support.

    you have installed on sda6 a Linux version which is not EFI-compatible.

    Ah yeah, I did, lol. I stupidly named the iso "xubuntu.iso" a while back and forgot what version it was !

    Works fine, except now Windows 7 doesn't work. On boot, it has 2 ubuntu options, then Windows 7 loader and Windows 7 Recovery, and Windows 7 Loader says "invalid efi file" or something like that. :/

    grub2's os-prober creates wrong style (BIOS) chain boot entry
    https://bugs.launchpad.net/ubuntu/+s...2/+bug/1024383
    type of entry from Boot-Repair that should work.
    'Windows UEFI loader'
    Type of entry that does not work:
    'Windows ...) (on /dev/sdXY)'
    Some info in Post #3 on cleaning up menus, if desired.
