When installing Ubuntu 18.04 LTS when the installation comes to the installation of "grub 2", it terminates and gives an error:

could not install the grub bootloader into target.

But the version of Ubuntu 16.04 LTS and other distributions are installed without such problems. Please tell me what to do?

    May be best to see details, you can run from your Ubuntu live installer or any working install, use ppa version not older Boot-Repair ISO: Post the link to the Create BootInfo summary report. Is part of Boot-Repair: https://help.ubuntu.com/community/Boot-Info and: https://sourceforge.net/p/boot-repair/home/Home/ Sometimes running Boot-Repair fixes reinstalls grub. Report will tell if installing UEFI or BIOS boot mode. – oldfred May 02 '18 at 23:09
  • What is the exact command you are using to install grub onto your system? Please edit this question and provide with more detail. – Terrance May 03 '18 at 05:01
  • Rather than installing `18.04` you can [clone your `16.04`](https://askubuntu.com/questions/1030268/how-to-securely-upgrade-ubuntu-from-16-04-to-18-04/1030348#1030348) to a test partition and upgrade it to 18.04 by rebooting to 16.04 clone and using `sudo do-release-upgrade -d`. You can repeat the cloning and upgrading many times until you are satisfied the new `18.04` passes the smell test. It might take a while. – WinEunuuchs2Unix May 05 '18 at 00:32

I had a same problem. Most likely you are missing ESP partition on your first drive.

-Start install again

-Chose "something else" option when prompted

-Resize your sda1 partition and mount it as root

-Make new partition of 100-200Mb and for type select ESP

This should solve your problem.

At the beginning of the partition division make room for installation. Prepare for ESP menu options and bootloader.

  • Your answer is a bit short. Please add some more information and guidance on how to do what you mentioned there, so that less experienced users can find it helpful as well. Thank you. – Byte Commander Jun 16 '18 at 16:26
