After installing Ubuntu 11.4 in a Macbook 5,2 I get a blinking folder with a question mark at boot.
The installation was successful erasing the entire drive, but the computer fails to boot Ubuntu, I launched the Live USB and inserted these commands in the terminal:
sudo apt-get install efibootmgr
sudo efibootmgr
sudo efibootmgr -o 0
Also modified the sudo nano /etc/default/grub
adding GRUB_CMDLINE_LINUX="libata.force=noncq"
And inserted this command:
sudo update-grub
However it returns:
cannot stat aufs
The blinking folder is still present.
How can I fix this?
