I'm having windows 10 and ubuntu 18.04 dual booted, when I try to boot to ubuntu then it directly opens windows 10, to overcome this I opened boot menu using F12 and then selected ubuntu from boot menu but still after selecting ubuntu it boots windows
To get into ubuntu I need a bootable USB each time and then from grub rescue I need to set root and prefix values each time, I also tried updating grub and another things mentioned in this, Can anyone suggest a solution for this so that I can get into Ubuntu easily without bootable USB.
PC details : Acer Nitro 5, EFI mode, GPT partition
Edit : I tried the suggested steps but issue is still unsolved
