    @Eric06
    Control of which system boots by default is controled by UEFI menu. So you need to directly go to UEFI and change boot order to ubuntu. This would be with UEFI on, and BIOS/Legacy/CHM off. Some work with secure boot on or off. All should work with secure boot on as Ubuntu's shim file has the Windows key, but some UEFI's are still not correct.
    When you go into UEFI/BIOS and change to BIOS you are booting a copy of grub2's boot loader that is in the protective MBR. An efi install does not have anything in the MBR as it is not nomally used.

    @ oldfred

    Thank you very much for your suggestion.

    As you suggested, I removed "boot" flag from any partition except sda1, using gparted. This did not fix the problem but now, I have an additional message at boot up: "start PXE over IPv4 [...]
    PXE-E18: server response timeout", then "start PXE over IPv6 [...] PXE-E18: server response timeout". Eventually, it gets back to "no boot device found". The boot-repair diagnosis after removing boot flags is: http://paste.ubuntu.com/5579906/ .

    Do you have any idea on how to move on from there?

    Thank you again,

    Sebastien

    Just like in BIOS you should have a choice of which physical devices to boot. It looks like you have the network device set as first hardware device to boot or in the mode you are booting the only one it sees. You need to be in UEFI not BIOS mode and choose ubuntu.
    Some of the new UEFI seem to have mixed the hardware and UEFI boot devices as one list, other have the hardware as one list and the software Windows or Ubuntu as another list somewhere in the UEFI menu.

    I have actually set up my BIOS (through the InsydeH2O Setup Utility) to UEFI Secure Boot and the only two choices I see when hitting F12 at startup are "UEFI Onboard LAN IPv4" and "UEFI Onboard LAN IPv6". Do you know how to change this?

    Thanks,

    Sebastien

    I do not know details, but Dell seems to be one that works reasonably well.

    Others that have worked. Maybe something they have posted will help.

    @oldfred

    Thanks for the links! I had actually gone through some of them and just checked the other ones, trying what made the most sense. But so far, I am stuck.

    I guess one option is to wait for the repair usb stick Dell is sending me and see if I can fix the boot from there (or in the worst case reinstall everything).

    One thing that surprises me, however, is that the double boot used to work, but stopped working (I guess after a Ubuntu update, but I am not sure). Also, at some point, after resetting completely the EFI/ubuntu and EFI/Boot in sda1 (following some comments in one of the link) by deleting manually and running boot-repair, I could see the Grub and boot to Linux, but when I restarted the computer, I lost again the access to any bootable media. Trying to repeat the same steps, I could not restore the boot anymore.

    Let me know if you have any more idea, otherwise I may wait for Dell usb stick.

    Thanks again,

    Sebastien

    I do not understand why from UEFI menu you do not see several options - Windows, Dell, Boot, ubuntu which are all the folders with efi boot files. You do have to have UEFI on, may be best to have secure boot off and BIOS mode off. Some UEFI system combine those settings in less than easy ways to tell what setting you really have.

    Also Boot-Repair names, renames or unrenames Windows efi file as some UEFI systems are hard coded to only boot the Windows boot file. You can run the unrename & then you should be able to boot Windows.

    @Olfred: Thanks for your reply, but this not helpfull to me, let me explain more:
    - I dont get any UEFI menu on my vaio s13 laptop (neither in the BIOS , or during the startup process)
    - I am trying to get what I had before a windows failure/recovery : boot in UEFI, get to the GRUB menu then Ubuntu (or windows from there)
    - as of today, under UEFI the machine will only go to windows.
    - my 'temporary bypass' to force booting on ubuntu is : (A) select 'legacy' boot (instead of uefi) in the BIOS, (B) boot a Grub2 CDROM, (C) from booted Grub2 cdrom boot my pc HDD

    my questions :
    - should i erase or modify parameters on one of my 2 EFI partitions ? (see initial append)
    - should i re-run boot-repair with specific options to fix my boot ?
    (and yes i know i can just reinstall everything, but i'd like to avoid this for just simple booting issue)

    Thanks for inputs and recommendations

    @everyone
    Best to start with secure boot off. Only some will work with it on, even though grub2's shim file has the Microsoft key and should work to secure boot on any system. Some UEFI hard code to only boot from Microsoft folder or Microsoft's efi file.
    Fast boot needs to be off. Vital for some systems.

    @Eric Sony may be one that only boots Windows, so either with Boot-Repair or manually have to copy & rename efi files.

    @Sebastien
    Not sure what to suggest. Some systems may auto restore or auto boot only Windows (see comments above). That is why Boot-Repair offers the renaming of files. But I thought Dell was one that worked.

    Thanks for the links. They seem to tell me what I already know... ... not providing a solution to the problem,however.

    I have had my doubts if booting from a lvm volume was a good idea... it now seems thoroughly confirmed.


    Ill try moving the partition out of lvm. Maybe bootdisk-repair will be more helpful without lvm.
