Macbook pro 7.1
triple boot using rEFIT
i recently installed ubuntu 11.10 on my macbook (new installation from cd), all perfect, but by mistake, i've installed GRUB into the default partition instead of the linux one. this gives me some little issue
here is the fdisk output
there's also the leopard partiton and the swap partition, but fdisk won't recognises it...
Device Boot Start End Blocks Id System
/dev/sda1 1 39 19+ ee GPT
/dev/sda2 40 409639 204800 b W95 FAT32
/dev/sda3 411648 49238015 24413184 83 Linux
/dev/sda4 * 49238016 133363711 42062848 7 HPFS/NTFS/exFAT
whatever, the point is
1 how can i precisely determinate in which partion grub2 is
2 how can i move grub from his partition to the linux one
help plz !
