Hi again, Get the grub-installer code to match the logs.... A new run of analyse in the install logs reveal :
neo:/home/bugdebian/log$ grep grub syslog Sep 26 14:50:35 anna[1964]: DEBUG: *retrieving* grub-installer 1.55 Sep 26 12:55:38 in-target: linux-doc-2.6.32 grub lilo Sep 26 13:09:41 main-menu[462]: INFO: Menu item 'grub-installer' selected Sep 26 13:09:41 *grub-installer*: info: architecture: amd64/generic Sep 26 13:09:42 grub-installer: info: Identified partition label for /dev/sda6: msdos Sep 26 13:09:42 grub-installer: dpkg: warning: ignoring request to remove grub which isn't installed Sep 26 13:09:42 grub-installer: dpkg: warning: ignobbring request to remove grub-legacy which isn't installed. Hey ! Where is the retrive of grub-pc ? If you call grub-installer without having retreived the grub-pc or grub+grub-legacy in /target, the only result is "Impossible to find'. That's the point ! Think you can find quickly the error, hope I will find the patch before you read my spams ! ;-)
