Ok, adding (hd2) /dev/md126 to target/boot/grub/device.map then re-running the grub-install works (it didn't find the windows install, but doing an update-grub from the running system fixed that). Like you I get the feeling that the source of the problem is that it's a mdadm raid using intel container format (aka fake raid). grub looks like it's trying to cope with either the old dmraid, or linux raid being handled by mdadm, but this case is beyond it's abilities. Would you like me to try debugging this further? -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org
