Some of my machines are booted with set timeout=5 menuentry 'Debian bullseye on 5740' { linux /vmlinuz root=LABEL=5740 ro quiet initrd /initrd.img } Perhaps you could try with this; maybe "root=/dev/sdaX" is more convenient. Also test with /vmlinuz.old and /initrd.img.old. Remove the first line to simplify the file. -- Brian.
