Arch Linux

os-prober entdeckt OS, aber kein Eintrag in grub.cfg

san04

Hallo zusammen,
parallel zu Arch habe ich auf einer weiteren Partition (p3) EndeavourOS installiert. Dieses wird auch von von os-prober gefunden:

~sudo os-prober
/dev/nvme0n1p3:EndeavourOS Linux (rolling):EndeavourOS:linux
~

os-prober habe ich aktiviert:

~cat /etc/default/grub | grep PROBER
# documentation on GRUB_DISABLE_OS_PROBER, if still want to enable this
GRUB_DISABLE_OS_PROBER=false
~

grub-mkconfig zeigt es an:

~sudo grub-mkconfig -o /boot/grub/grub.cfg
GRUB-Konfigurationsdatei wird erstellt …
Linux-Abbild gefunden: /boot/vmlinuz-linux
Initrd-Abbild gefunden: /boot/intel-ucode.img /boot/initramfs-linux.img
Found fallback initrd image(s) in /boot:  intel-ucode.img initramfs-linux-fallback.img
Warnung: Zur Erkennung anderer bootfähiger Partitionen wird os-prober ausgeführt.
Dessen Ausgabe wird zur Erkennung bootfähiger Programmdateien und Erzeugen neuer Boot-Einträge verwendet.
EndeavourOS Linux (rolling) auf /dev/nvme0n1p3 gefunden

EndeavourOS ist unverschlüsselt mit systemd-boot installiert, aber das sollte ja nur ggf. für Chainloading relevant sein? Habe hier aber auch testweise grub nachinstalliert.

Alles UEFI-only. Funktioniert os-prober einfach nicht mehr zuverlässig, oder wo liegt mein Fehler?

san04

Neuinstallation von EndeavourOS mit Grub als Bootloader führte dazu, dass der Grub von Arch das System direkt erkannt hat. Wundert mich etwas, da Grub doch auch andere Bootloader erkennen kann und selbst die Nachinstallation von Grub keine Verbesserung brachte, aber gut....
