I'm trying to install Ubuntu 17.10 on a HP laptop (Model:HP14bs547TU) as dual boot with Windows 10. Every time installation fails at the grub installation stage. It is giving me the following message

The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot.

I've never faced this kind of issue previously. How can I overcome it? Please help.

Thanks in advance.

  • Have you tried boot-repair from a live cd ? – An0n Feb 24 '18 at 2:25
  • No. How to do it? I'm trying to install using a USB Disk.@An0n – tuxtu Feb 24 '18 at 2:27

Boot Repair should fix this.

Use a live disk to boot. Then in a terminal enter following commands :

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

Click on Recommend Repair to fix the boot issues.


  • This solution works for me partially. But now I can only login to Linux. There is no way to login to windows now!!! – tuxtu Mar 1 '18 at 8:42
