I have installed Ubuntu 15.10 on Macbook Pro Retina late 2013. It was working well until I break the boot by reinstalling grub.Now I am not able to repair it.I have three partitions:/dev/sda1 - /boot - ext2 /dev/sda2 - / - root, ext4, enrypted with luks /dev/sda3 - swap, encrypted with luksI have no logical volumes there.I have tried to reinstall grub with initramfs to configure to boot in BIOS mode and was getting either blinking cursor and nothing happening or macbook into reboot loop.My configuration is:/etc/crypttab (unchanged as I had it from beginning)root UUID=***`<uuid of encrypted /dev/sda2>`*** none luks,discardswap UUID=***`<uuid of encrypted /dev/sda3>`*** none luks,discard,swap/etc/initramfs-tools/conf.d/cryptroot:target=root,source=UUID=***`<uuid of encrypted /dev/sda2>`***,key=none,discard/etc/initramfs-tools/conf.d/resume:RESUME=UUID=***`<uuid of encrypted /dev/sda3>`***/etc/default/grub (this configuration gives me blank screen with blinking cursor):GRUB_ENABLE_CRYPTODISK=yGRUB_DEFAULT=0GRUB_HIDDEN_TIMEOUT=0GRUB_HIDDEN_TIMEOUT_QUIET=trueGRUB_TIMEOUT=10GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`GRUB_CMDLINE_LINUX_DEFAULT=quiet splash nomodesetGRUB_CMDLINE_LINUX=cryptdevice=/dev/sda2:root root=/dev/mapper/rootGRUB_PRELOAD_MODULES=lvm luks cryptodiskGRUB_INIT_TUNE=480 440 1When I change to GRUB_CMDLINE_LINUX=cryptdevice=UUID=<uuid of encrypted /dev/sda2>:root root=/dev/mapper/root - I get into continuous reboot loopSteps I take:sudo sucryptdisk luksOpen /dev/sda2 rootmount /dev/mapper/root /mntmount /dev/sda1 /mnt/bootmount -o bind /dev /mnt/devmount -o bind /dev/pts /mnt/dev/ptsmount -o bind /sys/mnt/sysmount -o bind /proc /mnt/procmount -o bind /run /mnt/runchroot /mnt /bin/bashupdate-initramfs -k all -cgrub-install /dev/sdaupdate-grubexitrebootlsinitramfs /boot/initrd* | grep cryptsetup gives:sbin/cryptsetuplib/cryptsetuplib/cryptsetup/askpasslib/x86_64-linux-gnu/libcryptsetup.so.4Any ideas what I could be missing or doing wrong?
