From: mess-mate on 11 Jul 2010 19:00 Hi list, i've installed sqeeze (amd64) and grub2 as the boot loader. On an 2d hd lenny with grub (older version with the stage.. files) is installed. Since grub2 is installed on the mbr no way to boot my lenny system. Here is the lenny part on grub.cfg: menuentry "Lenny, kernel 2.6.28_mm01 (on /dev/sdc6)" { insmod ext2 set root='(hd2,5)' search --no-floppy --fs-uuid --set f26b56c1-4550-4815-b7bf-e5f114c6f9e4 linux /vmlinuz-2.6.28 root=/dev/sdc6 rootfstype=ext4 ro quiet vga=788 initrd /initrd.img-2.6.28 } UUID is disabled as default. any help would be very apprecited.

Have you tried the chainloader? I haven't so don't know but it seems like the chainloader should be able to boot your Lenny grub version. > Here is the lenny part on grub.cfg: > menuentry "Lenny, kernel 2.6.28_mm01 (on /dev/sdc6)" { > insmod ext2 > set root='(hd2,5)' > search --no-floppy --fs-uuid --set f26b56c1-4550-4815-b7bf-e5f114c6f9e4 > linux /vmlinuz-2.6.28 root=/dev/sdc6 rootfstype=ext4 ro quiet vga=788 > initrd /initrd.img-2.6.28 > } Unfortunately I don't know grub2 configuration well enough to suggest with any authority what the chainloader configuration would be. But looking at the web right now it appears that something like this might work. Untested. menuentry "Lenny" { insmod chain set root='(hd2,5)' chainloader +1 } Bob

I have had time when this process did not work, make sure os-prober is installed, on my Lenny it is 'suggested' for grub-pc. Squeeze works here though. If you use one mbr to boot all you will need to pick which os to configure grub. If you can't get to the one os you want to manage your disks use an alternate means to chroot into it, make sure os-prober is installed, then run 'update-grub'. -- Peace, Greg -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

So the lenny part was created as you can see above. I've checked a possible install of grub-legacy but it seems completely different from the one installed on lenny. ( no more stage files and so on) As you say, chrooting with a rescue-cd in lenny and setup a floppy grub loader would be a possibility. Had never a problem like this after a version change. |
