My Laptop: asus rog gl503ge. Dual boot with Ubuntu and Windows, where my ubuntu is installed in D drive.
Story: Recently, I have tried to install Ubuntu into a pendrive so I followed this https://www.tecmint.com/install-linux-os-on-usb-drive/ . But I didn't create a partition in the pendrive. After the installation completed, I removed the live usb but didn't remove the main usb where I installed the ubuntu. Now I rebooted it and when the GRUB showed up I found my dual boot and as well as the ubuntu in pendrive.
When I tried to reboot without the pendrive I ended with the grub terminal so I tried this method https://itsfoss.com/fix-minimal-bash-line-editing-supported-grub-error-linux/ and this worked fine for me but, my windows logo(in my case it's rog logo) went missing while booting. So, I tried to update my BIOS and thought it would work fine but, the another issue appeared.
Issue: As said above, I followed the itsfoss method for ubuntu and repaired my GRUB. Unknowingly when I installed my ubuntu as a dualboot I didn't create a efi partition and when I used the boot-repair tool I accidentally selected efi partition as windows efi partition. It was in advanced options and I didn't see that :( . So, My issue is whenever I tried to reboot again after repairing the GRUB using boot-repair tool also, I end up with GRUB menu only. But, if I reboot again I end up with GRUB terminal. And to my surprise I went to BIOS setting while booting again thinking of checking any error happened there and I found none so, I rebooted without any changes in the BIOS to my surprise I found GRUB menu when my laptop rebooted. But, when I rebooted without going into the BIOS I am getting stuck with GRUB terminal
Main Issue:when I rebooted without going into the BIOS I am getting stuck with GRUB terminal but when I go to bios and do nothing and boot the laptop I am getting GRUB menu.
Boot priority in BIOS: 1.Ubuntu 2.Windows
