Details:
Grub 0.96 installed on hd0, partition 3, /grub.
Grub 2.02 installed in /helenos/32/grub on hd0, partition 2.
In grub1 /grub/grub.conf:
title HelenOS
root (hd0,2)
kernel /helenos/32/grub/i386-pc/core.img
Selecting this entry while booting loads core.img:
Welcome to GRUB!
error: no such partition
Entering rescue mode ...
grub rescue>
Trying to list partitions:
grub rescue>ls
(hd0) (hd1) (fd0)
grub2 does not list any partitions!
consequently all found tutorials working with grub-rescue-mode fail:
grub rescue> set prefix=(hd0,2)/helenos/32/grub
grub rescue> set root=(hd0,2)
grub rescue> insmod normal
error: no such partition.
At this point you are lost. Since grub dos not find partitions (I could test
msdos and gpt both behave the same). It can not load any modules. I've tried:
to install grub2 using "grub-install /dev/sda2", then chainloading from
grub1:
> root (hd0,2)
> chainloader +1
> boot
same as before. Grub2 tells me "no such partition". I've even tried to put
grub into (hd0,2)/grub. But again without success. Same error again.
