salut,
je tombe également sur le message:
grub loading
error : no such disk
grub rescue >
Ma partition linux est en ext4 (je ne sais pas si ça peut avoire une influence).Je lance un shell à partir du live-cd 9.10 64. Aprés avoir monté ma partition linux 9.10:
root@ubuntu:~# fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xd03cd03c
Device Boot Start End Blocks Id System
/dev/sda1 * 1 7649 61440561 7 HPFS/NTFS
/dev/sda2 7650 7776 1020127+ 82 Linux swap / Solaris
/dev/sda3 7777 14150 51199155 83 Linux
/dev/sda4 14151 30401 130536157+ 7 HPFS/NTFS
Puis je fait un setup du grub(2). J'arrive à 'reconstruire' le grub avec la méthode suivante:
root@ubuntu:~# grub-setup -d /media/b6969e15-49be-41c4-8454-cea7f5b67e46/boot/grub/ -m /media/b6969e15-49be-41c4-8454-cea7f5b67e46/boot/grub/device.map /dev/sda
de cette manière j'arrive à récupperer le grub au reboot, mais dés que je quit une session Windows XP, au reboot le message "grub loading error : no such disk grub rescue >" réapprait.
voici une copie du fichier grub.cfg qui se trouve sur la partition 9.10.
