[SOLVED] Failed to install grub-efi-amd64 - LM19 v2.iso

[anber]

I have laptop HP pavilion 2018 year made and want to install Linux Mint 19 in dualboot.
Secure Boot is disabled in BIOS, I use latest linuxmint-19-cinnamon-64bit-v2.iso and live flash to install.

I manually create swap partition and ext4 as "/", and select as boot loader destination root of my HDD.

I faced with 2 issues:
1) It does now recognize my WiFi card during Live boot.
2) Install failed with message

Code: Select all

The 'grub-efi-amd64-signed package' failed to install into /target/.

Exactly like viewtopic.php?f=46&t=241379.

I tried all solutions what I can found on stackoverflow.com and this forum but still can't fix it.
I tried to enable Secure Boot - in this case it asks me to set up password in the first step of installation.
I tried to enable Legasy Boot but in this case it can't boot from flash.

How to fix it?

With UEFI, you need at least
1. One EFI-partition for a bootloader
2. One / partition

I was able to solve issue #2 with this article:

Shortly: you need wired network connection to finish installation.
It's a little bit strange, cause not every laptop has rj45 port now, fortunately my has and I also have router and cable, but I think that this is a critical issue.

But I still don't have WiFi on my laptop - no wifi option on Network manager and No suggestions from Driver manager.

Looks like there is no driver for my WiFi card (realtek d723) but some good guy post driver for it on his github repo:

So all problems are solwed.
But my girlfriend definitely could not solve it by herself
