I have a HD which has 3 partitions, in the following order:NTFSFAT32FAT32 (very small)I want to install GRUB into the MBR of the HD, and place the config files (menu.lst, etc.) into the 3rd partition.I will use the --root-directory command-line parameter.What happens if I change the partition layout after GRUB installation? Will GRUB be able to read those files, even if the partition they belong to becomes the 2nd or 4th one on the disk?
Does GRUB consider partition order when looking for config files?
boot;partition;grub
Grub will look at the partition table entries of your drive. So if you modify the drive in the future, you might have to both re-install grub to the MBR and update the config file so that each root entry points at the right partition.Also note that the partition numbering is different for old (the 'legacy' 0.9x) and new (1.9x) grub versions. The original grub counts partitions starting at 0, while the 'new' one starts with 1.
