Question

linux

Good day to all, help a novice Linux user deal with such a problem, when installing Linux Ubuntu 18.04 at the end it gives an error that GRUB cannot be installed, and the system will not be able to start.
The installation process looked like this:
1) From this https://www.ubuntu.com/download/desktop downloaded ubuntu and wrote it to a USB flash drive via rufus;
2) I started the installation process through the BIOS and selected the UEFI bootloader with my flash drive on which the OS is installed in the boot menu;
3) In the "Installation type" section, I chose another one and proceeded to the step where it was necessary to mark the disk, where I marked it as follows:
1) Created a swap partition (SWAP) with a volume of 9000 MB. with primary partition type and journaled Ext4 file system
2) Created a partition with a volume of 70000 MB of primary type, with a journaled Ext4 file system and a mount point "/ "
3) Created a partition with a volume of 800,000 MB of a logical type, with a journaled Ext4 file system and exact mount Home; (I gave away all the remaining space).
4) Then I completed all the following steps step by step and the installation process began, but at the end it gave an error that it was not possible to install "GRUP" and that the system could not be started.
5) After that, an attempt was made to install the OS again, but only in the section for choosing the type of installation, I chose the option to erase the disk and install the OS again and it became MIRACLE and earned.
PLEASE tell me what I did wrong, what is the error?

Answer 1

I do not see the ESP partition for the bootloader in the list.
> chose the UEFI bootloader
> where marked it as follows:
Markup type dos instead of gpt most likely chose.
Section ESP did not create.
Where will the bootloader be installed if there is no partition for it?

Answer 2

uefi if then a fat32 partition is created before ext4
you did not create it
