Dual boot on PC stopped working (Debian11 HDD grub + Windows11 SSD in grub list); how to solve?
by floppy_stuttgart from LinuxQuestions.org on (#6P2D1)
Hello,
since my PC did not boot anymore, I achieved a first step to make it booting again https://www.linuxquestions.org/quest...me-4175738776/
So, it boots into windows11 or Debian11 separately therefore no urgency.
However, the convenient HDD Grub menue boot (with line Debian11 and line Windows11) is not working again.
= I am trying to use the grub menue of the HDD again which show Debian11 line entry (for an HDD boot) and a Windows line entry (for the SSD boot). So far, not working again.
When I go to the BIOS setup advanced, choosing..
1. "Legacy Support Enable and Secure Boot Disable", the PC boot into Debian11 when the line Debian is choosen in the Grub menue; but by choosing the Windows menue line, it show the error "error: file '/efi/Microsoft/Boot/bootmgfw.efi' not found."
2. "Lecacy Boot Disable and Secure Boot Enable" or ".. Secure Boot Disable", it boot into Windows (no grub menue appear).
Few results of commands on the Debian11 booted PC:
efibootmgr -v
