I have the drive disconnected at the moment but, as far as I remember, ls (hd0,msdos1)/grub/ shows all the files that are normally expected to be there. That does not answer my question. File location differs between versions of GRUB. As I previously wrote, the version of GRUB up to Wheezy (1.99) installs *.mod files directly in (/boot)/grub whereas the version since Jessie (2.02) installs *.mod files in a subdirectory (/boot)/grub/platform. If the GRUB core image (not stored on the /boot partition) which boots searches files in (/boot)/grub/platform but the files are in in (/boot)/grub/ or the other way around, then there is a version mismatch. Didn't you install a more recent version of GRUB (possibly from a new installation) at some time on that disk ? Can you see the GRUB version which boots ?

I do not think there is a way of checking but the evidence for a version mismatch between GRUB and its modules seems strong. I would run a Wheezy installer image in rescue mode and reinstall GRUB to the MBR of the disk.

Thanks If the device and path for prefix is correct you should see a grub directory in the output of ls ((hd0,msdos1)/ Do you? It would be more usual for the prefix to be (hd0,msdos1)/boot/grub on a Debian machine with a standard installation.

Ldten K a écrit : Am trying to restore my regular working HD from backup HD but booting from the restored HD results in file '/grub/i386-pc/normal.mod' not found error. This seems a bit odd since 1) my wheezy system is amd64 Indeed this seems odd, but not for that reason. i386-pc is just the platform (PC BIOS), not the system software architecture. i386 and amd64 architectures both share the same i386-pc platform. The oddness is that AFAIK, the GRUB version 1.99 from Wheezy does not use the /grub/platform/ scheme yet but still puts *.mod files directly into /grub.
Wheezy amd64 grub2 error: file '/grub/i386-pc/normal.mod' not found
Hi, Am trying to restore my regular working HD from backup HD but booting from the restored HD results in file '/grub/i386-pc/normal.mod' not found error. This seems a bit odd since 1) my wheezy system is amd64 and 2) I can boot from my backup HD just fine. My regular working and backup HDs have the same size, the same partition structure and, at least in theory, the same data. I used dd to copy /boot partition data between my regular and backup HDs: ## backup /boot partition. Booting from the backup HD works fine. # dd if=/dev/sda1 of=/dev/sdb1 conv=sync,noerror What I tried: 1. Reinstall grub on the main HD (/dev/sdb, as the system is running off the backup HD which for now is /dev/sda). Did not help, the same file '/grub/i386-pc/normal.mod' not found error persists. ## /dev/sdb1 is /boot partiion # mount /dev/sdb1 /mnt/1 # grub-install /dev/sdb --boot-directory=/mnt/1 2. In the grub rescue mode: grub rescue set prefix=(hd0,msdos1)/grub grub rescue insmod normal file '/grub/i386-pc/normal.mod not found grub rescue insmod linux file '/grub/i386-pc/linux.mod not found Any ideas?
