Clonezilla clone won't boot without reinstalling grub2

I've taken a clone of a machine with the following partitions: Device Type Label /dev/sda /dev/sda1 Ext4 boot /dev/sda2 Linux LVM /dev/system/ LV system /dev/system/home LV home /dev/system/root LV root /dev/system/swap LV swap These are referenced by label in /etc/fstab: LABEL=root / ext4 LABEL=boot /boot ext4 LABEL=home /home ext4 LABEL=swap /swap swap and grub.cfg: menuentry 'openSUSE, with linux ' --class opensuse --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux--simple-' { insmod ext2 set root='hd0,msdos1' linux /vmlinuz- root=/dev/mapper/system-root resume=/dev/disk/by-label/swap initrd /initrd- } I am trying to install this clone on another identical machine. The install succeeds, but I can't boot into the machine without doing the following in the grub prompt it dumps me into: grub> set root=(hd0,1) grub> linux /boot/vmlinuz- root=/dev/sda1 grub> initrd /boot/initrd.img- grub> boot I'd much prefer to get an image which does not require these steps, but I'm not sure where the problem lies (grub config, other system files, clonezilla). Things I have tried so far: - Edited /etc/defaults/grub and uncommented 'GRUB_DISABLE_LINUX_UUID=true' - Edited grub-mkconfig_lib to comment out the lines like search --no-floppy --fs-uuid --set=root ${hints} ${fs_uuid} to prevent them being added when grub.cfg is generated - (and re-generated grub.cfg) - Selected advanced clonezilla install and told it to re-install the MBR afterwards (option -j1. option -g auto "Reinstall grub in client disk MBR" was already selected by default) Any other things I can try? I did notice that /boot/grub2/device.map lists "sda1" for hd0, but the HD of the other machine is being detected as sda1 when I install the clone so I don't think this is likely to be the culprit. (I wasn't sure if here or Superuser was the better fit for the question, I am happy for it to be migrated as appropriate.)
