Ubuntu login issues via Grub

Please describe, what there is happening when you switch on the system and try starting Ubuntu.

/boot/grub/device.map shows an error. When I press login to Ubuntu, there
is a lot of information on the screen, then a black screen and a blinking
cursor. When I enter through the kernel, the bootloader panel opens and OK
on the first line I enter the system. I do not understand why the Ubuntu
menu does not work?

"/boot/grub/device.map shows an error."
What kind of error?

"When I enter through the kernel"
What do you mean by "enter through the kernel"?

When you boot the system, how do you choose to start Windows or Ubuntu?

Do you see the grub menu when you start the system?

Yes, I see the standard menu, but the login through Ubuntu fails (shows a
lot of information, then a blinking cursor and that's it.
 When I press enter through the specified kernel, I go through the
bootloader menu by function normally

In your other question https://answers.launchpad.net/ubuntu/+source/linux/+question/703966 I see that you tried adding "nomodeset" to the grub parameters. There are some reports of people who tell that their system does not correctly boot with the "nomodeset" parameter (especially systems with NVidia graphic cards).

Why did you add nomodeset?

I had it by default, I did not change anything

Why did you add nomodeset?
"I had it by default, I did not change anything"

That cannot be true. The whole problem in the other question has been caused by an incomplete addition.

and what to replace this nomodeset with?

GRUB_CMDLINE_LINUX_DEFAULT nomodeset is now in the bootloader, as it was.
We have only corrected the quotes in the file of the above operations to
fix the kernel bug

The default value delivered by Ubuntu before any modification is

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

should I replace monodesept with quiet splash in the grub bootloader
itself? Now grub shows an error in the DEVICEMAP-FILE:
/boot/grub/device.map How to do this correctly? I think - go to grub,
Ubuntu-File-Edit , change monodesept to quiet splash and save, right or not?

"Now grub shows an error in the DEVICEMAP-FILE: /boot/grub/device.map"
Repeating: Which "error" does it show?

And yes, I recommend that you update the contents of /etc/default/grub again, giving "quiet splash" (with quotes!) after the equal sign of GRUB_CMDLINE_LINUX_DEFAULT

After changing the contents of /etc/default/grub you have to run the command
sudo update-grub
to apply the changes, and then reboot to verify what the effect is.

** (gedit:19707): WARNING **: 20:24:29.704: Failed to set document
metadata: Setting metadata attribute::gedit-position is not smart This is
displayed in the terminal after changing file line 10 ..quiet splash I have
not yet updated grub - what to do next?
