I had both ubuntu 18.04 and windows 10 on my PC, I was using grub (or grub2, can't tell now) to switch between them. I decided to reinstall ubuntu, I have chosen not to upgrade from ubuntu 18.04 to 20.04, but to fresh install ubuntu 20.04 over 18.04. So I created an ubuntu usb stick and installed from it. I do not remember my choice for boot loader destination, I think I have left this field as it was with a prompted destination. After that, the grub loader was gone, my PC booted directly into ubuntu.

I have tried:

  1. ubuntu boot-repair First I ran it with default options with no luck, then I choose advanced options - purge and reinstall grub, it finished with an error, and here is the link to the log: http://paste.ubuntu.com/p/7qvF4tCV7V/ boot-repair told me that I can post this link to a forum, so here I am.

  2. I created a windows 10 installation usb stick, tried to troubleshoot with it, but with no luck. It told me that it cannot handle the problem. here is the log: https://txt.online-reader.com/view?f=PX3sk45

Please, point me in the direction for my next actions, I am out of ideas right now.

Start the Ubuntu in the Terminal program use nano /etc/default/grub to edit the file. Change the hidden to menu and the timeout value to anything other than 0 to have a countdown of that many second before it boots the default OS. Once done the editing then sudo update-grub to have the changes written to the disk and used on next boot. You should now have the grub menu back the Ubuntu people so helpfully disabled by default...

This is the answer: Grub menu working but hidden, can't make it visible

After I set GRUB_TERMINAL=console everything started to work just fine. Hell, can't believe I wasted the whole day fixing this. Holy crackers.
