My laptop used to dual boot normally, but after I updated windows 11 yesterday, the laptop does not allow me to select the OS to run. It starts straight to windows 11. I tried this but couldn't solve the problem. What can I do?

Thanks @user68186, but this could not answer my problem. However, I managed to get the grab manually. The problem now is that I have to do it manually either way it will just go straight to windows 11. – Patrick TSHABA Feb 13 '23 at 16:09

Trying to solve this, I could only manage to get the GNU grub manually. I doesn't come up automatically as it's supposed to. This is how I did: – Patrick TSHABA Feb 13 '23 at 16:14

Read all the answers. First: Boot Repair in Ubuntu after manually booting Ubuntu. Or better, boot from the Live Ubuntu Install USB using the Try Ubuntu option (Do not install Ubuntu). Once Ubuntu boots install the boot-repair app following instructions in the links above. Then click on the Recommended Repair button. – user68186 Feb 13 '23 at 16:26

Here is another possible duplicate of this question with various solutions to try: Windows 10 upgrade kills grub and boot-repair doesn't help. – user68186 Feb 13 '23 at 16:35

Could you check boot order or boot priorities on BIOS(UEFI) menu? Maybe, you can select OS.
I also faced similar situation. But, in my case, Ubuntu wake up. So, I tell the way to allow OS selection on grub menu from Ubuntu side. Grub 2 does not detect otat default. Please try rm /boot/grub/grub.cfg and sudo update-grub. Maybe, update-grub will find Windows boot manager. Then, you can select OS on grub menu.
