I am trying to reinstall GNU GRUB 1.97~beta4 on an Ubuntu WattOS RC1 (/dev/sda) / Debian 6 (/dev/sdb) dual-boot system.
sudo fdisk -l Disk /dev/sda: 200.0 GB, 200049647616 bytes 255 heads, 63 sectors/track, 24321 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000001 Device Boot Start End Blocks Id System /dev/sda1 * 1 23572 189342058+ 83 Linux /dev/sda2 23573 24321 6016312 5 Extended /dev/sda5 23573 24321 6016311 82 Linux swap / Solaris Disk /dev/sdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00060463 Device Boot Start End Blocks Id System /dev/sdb1 1 38127 306246656 83 Linux /dev/sdb2 38127 38914 6322177 5 Extended /dev/sdb5 I mount dev, proc, sys, and usr on /dev/sda (aka w1), and guest@guest:~$ sudo chroot /mnt/w1 /bin/bash root@guest:/# update-grub2 root@guest:/# grub-install /dev/sda /usr/sbin/: Not found. I'm stumped. I have previously done root@guest:/# grub-install /dev/sda1 getting ... init[1]: segfault at 0 ip (null) sp bfd65e44 error 4 kernel panic - not syncing: Attempted to kill init ! Pid: 1 comm: init Not tainted 2.6.31-23-generic # 75-Ubuntu .. but have since become aware I should not specify partition number. Inspecting files on the WattOSRC1 drive (w1), it seems I have two GRUB folders guest@guest:/mnt/w1$ ls bin debootstrap grub initrd.img.old man1 openbox proc sbin sys var boot dev home lib media opt resolv.conf selinux tmp vmlinuz cdrom etc initrd.img lost+found mnt opt1 root srv usr vmlinuz.old and guest@guest:/mnt/w1/boot$ ls bin debootstrap grub initrd.img.old man1 openbox proc sbin sys var boot dev home lib media opt resolv.conf selinux tmp vmlinuz cdrom etc initrd.img lost+found mnt opt1 root srv usr vmlinuz.old The best way to get a working dual-boot GRUB2 seems to be to delete one of the grub folders, and tell GRUB2 where the kernel and root fs are. I have been messing around with rescue prompt boot instructions and have been able to boot into the debian drive, initially in graphic (with stationary mouse) and later in text mode, but it seems a bit hit and miss, lately mostly miss. Dunno why .. maybe too many changes. I'd appreciate any constructive advice as I am about to move house and will be off-line for a while. I'm starting to appreciate Live-CDs.
