I recently installed Debian stable and now after boot I get a grub command line instead of the usual menu. When I run configfile (hd0,gpt6)/boot/grub/grub.cfg, I get to the grub menu and see that Debian as well as Widnows are listed there, so grub seems to be installed correctly. I know that there many questions around this already, so here is what I have tried already to solve the issue:

  • Boot into a boot-repair-disk and run recommended repair from there
  • Manually mount the system from a live disk chroot into it and install grub
  • Following this, I ran update-grub and install-grub /dev/sda
  • Also tried grub-mkdevicemap, grub-install /dev/sda, and then update-grub

None of this worked, I still get the grub prompt after booting.

I have a dual boot setup with Windows on another partition. Secure boot is disabled. Before I installed Debian on this partition I had another distro installed on it and the grub menu worked fine.

Solved it, I seems like the boot manager was still loading the Ubuntu grub and the Debian grub was not included. I just has to execute bcdedit /set "{bootmgr}" path \EFI\debian\grubx64.efi from Windows PowerShell.
