Ubuntu: Manual intervention required for booting - How do I automate this?


I have Ubuntu 12.04 running exclusively on my aspire one 756 netbook, I downloaded the 64bit iso and made my install on a usb-stick.

First issue: it did not boot automatically from that stick, I had to choose the usb efi device manually to boot and install from. However the installation went fine

Now the system won't boot normally and I always need to choose the efi part manually to boot.

The bios (updated yesterday to v1.09) and has no 'legacy boot' nor a 'secure boot' option to choose from. The grub update with "boot=efi" made no changes.

Is there a solution to automate this?

thanks in advance

update: i've run boot-repair over it. maybe it helps boot-repair info


One part of the answer is from Acer saying 'if you are on BIOS 1.x, stay on 1.x'

A german Acer forum gave me the advice to do a low-level-format prior to installing the x64 version. I have not tested this, as I'm back to 32bit (up and running smooth).


Try this, in Ubuntu:

sudo efibootmgr -o 0,3,4,1  

If that doesn't work, then I have three other suggestions:

  • Run the Ubuntu Boot Repair tool. I'm not 100% positive that it will work in your case, but it might.
  • Type sudo mkdir -p /boot/efi/EFI/BOOT; sudo cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/BOOT/bootx64.efi. This will copy GRUB to a fallback/default EFI boot loader filename that might work.
  • Download and install the Debian package version of my rEFInd boot manager, then type sudo mvrefind.sh /boot/efi/EFI/refind /boot/efi/EFI/BOOT. This will put rEFInd in the fallback/default boot loader position. If that doesn't work, try typing sudo mvrefind.sh /boot/efi/EFI/BOOT /boot/efi/EFI/Microsoft/Boot. This last command copies rEFInd to the default location used by the Windows boot loader, which some very badly-written EFIs insist on using.

You can try these in any order you like, although I've listed them in increasing order of complexity.
