This question is transcribed into English, there may be a wrong word.

The laptop I’m using is an asus x441u series.

I just finished installing ubuntu 24.04, I’m using dual boot, when I finished I was directed to reboot the laptop.

then this message appears
enter image description here

I followed this suggested method but it didn’t work.

I see people suggest fixing in EFI with Efibootmgr, I see people use terminal in ubuntu but how do I do it while I can’t access to my ubuntu.

I hope there is someone who can help me who is a beginner who wants to use this linux.
