    Hi there!


    A little background:

    I bought an Aspire ES1-533-C4WF and faced the same problem. The workaround proposed here by Sladek90 and Pueseso was exactly what I needed. Unfortunately it did not go well. I think it can not work any more because the ESP (EFI System Partition) is damaged. Maybe it was damaged by my previous attempts, before I found this thread. One idea would be to try and fix it but this will take a lot of research. It would be easier to just format the whole disc (including the ESP) and install Ubuntu from scratch. I did not dare to do it yet because I have been warned that this could be dangerous and brick my new laptop. Maybe I am being silly but please bear in mind that this UEFI thing is new to me, I have been warned to be careful with it and frankly it has not been kind with me so far...


    So my (double) question is:

    1) Is it safe to format the whole disk, including the ESP, and install Ubuntu?

    2) Can the Ubuntu installation process recreate the ESP?

    Note that after the format I will still have to follow this thread's instructions, with "obiquity -b" and so on, and not a normal linux installation, but let's supose that I will do it right this time.

    1) It is absolutely safe to format complete disk erasing also the ESP. I have done it at least 10 times during my attempts to install linux and finally the computer works well. ESP is in fact nothing special but usual disk partition.
    2) The ESP can be recreated automatically from within the Ubuntu installer or you can do it manually by some partitioning tool as for instance Gparted. There are lots of guides on how to partition your hard drive for linux EFI installation across internet.

    Wish you successful installation.

    I knew it! They got me scared for no reason. Thank you Sladek90! I will do it first thing in the morning.


    ----- EDIT -----

    It worked perfectly, no need to change anything. Kudos to everyone who worked for it.

    Won't work. Tried it already with VN7-793G. Bootloader doesn't seem to find any Windows 7 installation.

    I have had the same problem and I just solved it. Downgrade your BIOS version to BIOS Improve System Performance" from the link below. Then you would be able to change the Boot mode from UEFI to Legacy.

    I have successfully installed Ubuntu 16.04.1 in my laptop ES1-533-C6C1 following Sladek90 advise.

    The only drawback is that it is horribly slow (probably becouse of some bug, have tried a Live-USB with MINT and it was OK...

    This is the full tested process:


    -- Boot Ubuntu Live USB

    -- open terminal

    sudo -s

    ubiquity -b

    -- Press Continue testing after installation is over.


    --Now we will return to the CLI (  https://wiki.debian.org/GrubEFIReinstall  )


    sudo mount /dev/sda2 /mnt #sda2 is the root partition

    sudo mkdir /mnt/boot/efi

    sudo mount /dev/sda1 /mnt/boot/efi #sda1 is the efi partition

    for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done


    modprobe efivars # make sure this is loaded


    -- notice the bootx64 file

    efibootmgr --verbose


    -- We will reinstall grub-install for a 64bit version

    apt-get install --reinstall grub-efi-amd64


    grub-install —no-nvram —root-directory=/mnt

    chroot /mnt


    cd /boot/efi/EFI

    cp -R ubuntu BOOT

    cd BOOT cp grubx64.efi bootx64.efi


    -- You are finished, reboot the system.

    After much troubles and looking around on the internet when wanting to install Ubuntu on a Acer Aspire, I found this topic. And it works, almost. I do get the installation completed, where using other methods it crashes at installing grub2. But I have problems when I give the command

    grub-install --no-nvram --root-directory=/mnt

    This error occures then:

    grub-install: error: install device isn't specified

    It seems I need to add a place on de harddrive? Could you help out?
    I hope someone can help me out, untill now I have not found a solution yet.

    Hi I tried that with no luck. Actually, the secure boot is displayed as Disabled, but BIOS still requires supervisor password before entering the BIOS editing tool... Before setting Supervisor password access to BIOS was not restricted, now the password is required to access BIOS settings edit and Secure boot disable/enable seems to have no effect on that.


    Anyway, the main problem - that UEFI is the only option in Boot Mode - still persists. Secure Boot settings didnt change anything.

    thx Jirka

    Same issue someone help...............
