I have a MacBook 7,1 and I am attempting to configure 2 ssd's in RAID 0, with a fresh install of (64)Mint 18.1 xfce on top.
I used this tutorial -> https://forums.linuxmint.com/viewtopic.php?f=46&t=138044#p735417
as reprinted in Full Circle mag Issue #104
Everything has been peachy until just before time to reboot. After chroot, it will not allow me to install Grub into my new filesystem. It gives me the error : cannot find EFI directory
-> this gives me the error: cannot find EFI directory
sudo grub-install --efi-directory=/boot/efi --bootloader-id=linux-mint
-> gives me error: /boot/efi doesn't look like an EFI partition
I have researched to the best of my noob ability and tried a couple things resulting in varying degrees of failure. If I simply reboot, not only can I not boot back up, but booting from the a LiveUSB shows that Mint was not even installed. It should be noted that I do not get the screen informing me to remove the installation medium and press 'enter'. I tried installing rEFInd instead, which seems to install ok and even allow the installation to complete upon reboot (although, still no 'remove medium and press enter' prompt) but then I cannot boot through rEFInd and must resort to my LiveUSB. I have no idea why this would happen if rEFInd was installed after chroot.
I am currently stuck post installation but pre-reboot, trying to install grub so I can restart to complete the Mint 18 install and reboot normally w/o the LiveUSB. Thanks you for any help. I am very much a noob so forgive me if I am all confused but I am determined to learn.
