    It looks like you left Windows fast startup on. You need to have that off.

    Acer do not need the suggested fix by editing BCD in Windows.
    But they need you to set a supervisory password and set "trust" on the Ubuntu boot files.

    Re: dual boot xubuntu windows 7 problem

    Many many thanks Oldfred and for the very quick reply
    I am a 9 years passionate ubuntu user and I never found such a complicate issue
    it took me 8 hours to solve (for sure my skills do not help...)
    I am surprised that Acer created such a ridiculously complicates setting, microsoft is not enough, we need also the manufacturers messing around...

    I solved through these links

    not sure turn off windows fast start-up necessary
    for sure not necessary disable Secure Boot in bios in my case <a lot of advice stress the importance of this

    I try to recap my solving (for computer laptop acer E5-571-57H1)
    (after installed xubuntu)

    turn on and press F2, bios come up (mine called InsydeH20 setup utility rev. 5.0)
    go to page Security
    go to "Set Supervisor Password" press ENTER (I set pass "a")
    go to "Select an UEFI file as trusted for executing:" press ENTER
    a new page appear with listed:
    HDD0
    HDD0

    press ENTER on the first HDD0 and see if a sub list with the name "<EFI>" comes up (in my case did not show <EFI> but: recycle bin and system volume info)
    press ENTER on the second HDD0 and see if a sub list with <EFI> comes up (in my case showed <EFI> and <boot-sav>)
    press ENTER on <EFI>, new list comes
    press ENTER on<ubuntu>, new list comes with:
    shimx64.efi
    grubx64.efi
    MokManager.efi

    press enter on each one and give them a for you recognizable name (I used "xubuntushimx64efi", "xubuntugrubx64efi", "xubuntuMokManagerefi")
    and press Yes

    save and exit

    go back in bios f2

    go to "Set Supervisor Password" and set pass to nill-blank (you want to eliminate a not necessary password that you could forget...)

    go to "boot page" tab
    you should find the named shimx64.efi, grubx64.efi, MokManager.efi
    bring them up in the priority boot list (above windows if you want ubuntu default system)

    go to page main - enable F12 boot menu
    save and exit

    now ubuntu should be your main boot and if you need windows press F12 at start and select...

    madness!!!!!
