Hi, got an odd problem, GRUB 0.95 and 0.97 mysteriously refuse to boot beyond stage 1.5 on an nForce4 chipsetted mobo (Asus A8N-SLI Deluxe).
I've tried several parallel ATA disks (40GB, 120GB, 250GB), and also using a /boot partition at the start of the disk instead of just a single / plus swap, but to no avail. When I move the exactly same test disks created on the A8N-SLI PC to different PCs (tried 2), they boot just perfect on those, with GRUB menu and all. Even when installing Fedora Core 5 or Debian 3.1 on the A8N-SLI PC, the entire setup process completes fine, but upon reboot grub gives alternatively errors 16, 18 or 25. Wiping the beginning of the disk with dd if=/dev/zero for a few blocks, then reinstalling e.g. FC5, the problem still persists. So on the A8N-SLI Deluxe apparently no matter what, GRUB gets stuck on stage 1.5, no menu. Any ideas? I already did update-grub, grub-install /dev/hda --recheck, after booting with a recovery CD and chrooting to /dev/hda. Grub appears to install itself just fine, but booting still gives those errors. Any thoughts on what to try next? Some grub info (though I'm not sure if this is GRUB config issue since the same disk will boot to grub menu properly on a different PC...): ------ /boot/grub$ cat device.map (fd0) /dev/fd0 (hd0) /dev/hda (hd1) /dev/sda (hd2) /dev/sdb (hd3) /dev/sdc (hd4) /dev/sdd ------ /boot/grub$ cat menu.lst (snipped the comments) default 0 timeout 15 color cyan/blue white/blue # kopt=root=/dev/hda1 ro bigphysarea=16000 ide=nodma # groot=(hd0,0) # alternative=false # lockalternative=false # altoptions= # howmany=all # memtest86=true title Debian GNU/Linux, kernel 2.6.17.4gofrito1 root (hd0,0) kernel /boot/vmlinuz-2.6.17.4gofrito1 root=/dev/hda1 ro bigphysarea=16000 ide=nodma initrd /boot/initrd.img-2.6.17.4gofrito1 savedefault boot title Debian GNU/Linux, kernel memtest86 root (hd0,0) kernel /boot/memtest86.bin boot ----- /boot/grub$ sudo fdisk -l /dev/hda Disk /dev/hda: 40.9 GB, 40982151168 bytes 255 heads, 63 sectors/track, 4982 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 1824 14651248+ 83 Linux /dev/hda2 1825 2189 2931862+ 82 Linux swap / Solaris /dev/hda3 2190 4982 22434772+ 83 Linux ----- thanks, - Jan _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
