Failed to login even to terminal somehow enter is pressed

Question

I fail to even log into recovery terminal, after I roll back to 4.4.0-142-generic kernel (because of error in nvidia driver in 4.4.0-143-generic kernel) after grub update. I login and then somehow additional enter is pressed and voilà, I have brick instead of PC.

How to enter GRUB? I PRESSED left and right shift with no luck at all what is going? — Marat Zakirov, Mar 25 '19 at 11:14
Toggling left <Shift> many times just after BIOS splash would work. — N0rbert, Mar 25 '19 at 11:15

You need to select Advanced options for Ubuntu and choose previous kernel. See second screenshot https://askubuntu.com/a/92558/66509 . So you need to reboot machine, hold key and enter Advanced options for Ubuntu menu in GRUB. — N0rbert, Mar 25 '19 at 12:14
@N0rbert Shift does not work in my case but ESC does the problem is that Grub menu exists only 0,5 of a second and i can not choose anything BUT i have grub terminal and can do something from it, the quastion is csn i load from kernel i need? — Marat Zakirov, Mar 25 '19 at 12:20

I solved this issue by pressing and and praying to select other option to boot. I succeed and ffter it select 440-142-generic kernel and boot with it

I set GRUB_DEFAULT='Advanced options for Ubuntu>Ubuntu, with Linux 4.4.0-140-generic' in /etc/default/grub file update-grub reboot
