Hello,
I am running a tri-boot with EndeavourOS, Windows 10, and Pop OS on an old pc I have for fun. I had recently installed Pop OS, which overwrote the bootloader with systemd-boot, so I chrooted into EndeavourOS and reinstalled GRUB. I could then boot all OSes.
later, after booting into Windows, I got a "no boot device" error on restart. I used SystemRescue to chroot into EndeavourOS and reinstall GRUB, but it still said that error. I also tried booting into EndeavourOS directly from SystemRescue and reinstalling GRUB, but it did not work either. What should I do?
