Today i endly decide to put a Linux in dual boot on my macbook 7.1 I parted the HDD with Gparted like this :
refit / MacOSX / boot / root / home
I installed Arch succefully, folowing the tuto about the macbook specific install. When it ends with the bootloader install screen i get an issue, i simply can't select the boot(/dev/sda3) partition to install GRUB in it - it only propose sda..
Then i reboot, try to sync the partition table with REfit but it says it's ok... Sounds weird but ok, i put a Ubuntu LiveCD in my macbook and reboot with it. Try to install Grub this way but it desn't work too :
ubuntu@ubuntu:~$ sudo grub-install --root-directory=/media/4d63602e-5572-4279-bee8-026a94932e91 /dev/sda3 /usr/sbin/grub-setup: warn: Attempting to install GRUB to a partitionless disk or to a partition. This is a BAD idea.. /usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged.. /usr/sbin/grub-setup: error: will not proceed with blocklists. ubuntu@ubuntu:~$
I'm pretty out of ideas to solve this, any clue guys ?
