Hi there! This could be a duplicate of #650724, but given that the error shown is different, I reported it as a new bug. I changed both 500GB Samsung HDs with two 1TB Seagate HDs (in RAID1, LV for /), in series: changed the first, rebuilt the RAID1, checked that everything was OK, reconfigured grub-pc for the new disk and then started again for the second, but it seems I missed the second 'dpkg-reconfigure grub-pc' step and the last kernel upgrade fails: ===== tinello:/etc# apt-get update [...] tinello:/etc# apt-get upgrade [...] The following packages will be upgraded: linux-image-2.6.32-5-amd64 [...] Preconfiguring packages ...

I think there is a fundamental problem here: grub-pc's debconf mixes device names (/dev/sda) with device IDs (/dev/disk/by-id/...). This means that while you think you chose device names (so changing disks should not cause any problem), what is actually used is device IDs, which are not updated *before* starting grub-probe (so your choice is not taken into account). Indeed, updating this line was enough to solve the problem: ===== tinello:/etc# echo "grub-pc grub-pc/install_devices string \ /dev/disk/by-id/ata-ST31000524AS_6VPC7CTQ, \ /dev/disk/by-id/ata-ST31000524AS_9VPCW9CS" | debconf-set-selections tinello:/etc# dpkg-reconfigure grub-pc [...] ┌─────────────────────┤ Configuring grub-pc ├─────────────────────┐ │ The GRUB boot loader was previously installed to a disk that is │ │ no longer present, or whose unique identifier has changed for │ │ some reason.
