This works with the partition table of the initial bug report: /home/fz/grub/grub2-1.96+20090725/kern/partition.c:106: Detecting pc_partition_map... /home/fz/grub/grub2-1.96+20090725/kern/disk.c:389: Reading `hd1'... /home/fz/grub/grub2-1.96+20090725/partmap/pc.c:153: partition 0: flag 0x0, type 0x5, start 0x0, len 0x11177330 /home/fz/grub/grub2-1.96+20090725/partmap/pc.c:153: partition 1: flag 0x0, type 0x0, start 0x0, len 0x0 /home/fz/grub/grub2-1.96+20090725/partmap/pc.c:153: partition 2: flag 0x0, type 0x0, start 0x0, len 0x0 /home/fz/grub/grub2-1.96+20090725/partmap/pc.c:153: partition 3: flag 0x0, type 0x0, start 0x0, len 0x0 /home/fz/grub/grub2-1.96+20090725/kern/disk.c:389: Reading `hd1'... /home/fz/grub/grub2-1.96+20090725/kern/partition.c:112: pc_partition_map detection failed. /home/fz/grub/grub2-1.96+20090725/kern/disk.c:333: Closing `hd1'. -- Felix Zielcke Proud Debian Maintainer _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
