Grub ubuntu won't load. What to do with it?

Question

linux

I installed an additional Ubuntu on a laptop running UEFI with the Windows 10 operating system, but when the computer is restarted, Windows starts automatically, there is no hint of Grub.
For Linux, I allocated an empty space in Windows, which I already distributed in the installer into two directories.

You need to go to the boot menu in bios and put ubuntu first in the list. How to do this depends on the bios. Then the grub menu will be displayed. If after that there is no Windows item in grub, then you need to execute in ubuntu:
sudo update-grub
or
sudo update-grub2
(most likely it doesn’t matter).
