I have Windows 10 and I am trying to install ubuntu 18.04.1 with no success. Here is my system info:

  • HP Envy x360 Laptop with SSD (with GPT)
  • I have 100 MB EFI System parition (installed with Windows 10) Here is my Disk Partition table
  • Windows 10 is installed in UEFI mode
  • Windows 10 Fast Reboot is disabled
  • From BIOS Secure Boot is disabled
  • ubuntu 18.04.1 ISO copied to USB using Rufus 3.1 in GPT mode
  • On restart ubuntu USB loads fine as I clicked on 'Try ubuntu'
  • Once ubuntu is running then I click on Install ubuntu
  • And then I get this error:

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

I have tried many times by selecting/deselecting options like 'install 3rd party drivers', 'install updates during installation' but I always get the same error.

I have searched on web and many users are facing the same error and I have tried to apply some fixes / workarounds (like disabling Fast Reboot , disabling Secure Boot etc) but none worked in my case. I have even tried increasing the EFI partition size to 500 mb but I still got the same error.

Could someone please suggest a solution for this problem. I thought ubuntu is a friendly Linux distro and its installation will be as easy as installing Windows... but its giving me some pains....

I would really appreciate some help here.

EDIT:

Here is my Parted -l result

Thanks, Maverick

  • Some have needed chkdsk on ESP from Windows or dosfsck from Linux on the ESP partition. `sudo dosfsck -t -a -w /dev/sda2` Then try fixing with Boot-Repair. https://help.ubuntu.com/community/Boot-Repair – oldfred Aug 26 '18 at 18:24
  • I tried this too... still the same error :( – Dany Sep 01 '18 at 06:45

I would boot into the Ubuntu Live without installing and in terminal do one line at a time 

sudo mkdir -p /mnt/boot/efi
sudo mount /dev/sda7 /mnt
sudo mount /dev/sda2 /mnt/boot/efi
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt
apt-get update
apt-get install --reinstall grub-efi grub-efi-amd64 grub-efi-amd64-signed
os-prober
update-grub
exit
Then see if you can boot into the install
