Well, like it said on Link2SD app description:
You should have two partitions on SD card and both should be primary.
The first FAT partition is your standard SD card storage. The second partition is used for application files and can be ext2, ext3, ext4 or FAT32.
Some phones lack the ext2, ext3 or ext4 file system support and you may get mount errors like "no such device", "invalid argument". These phones need ext2.ko or ext3.ko modules and even some additional modules to be able to mount. Using FAT32 on the second partition will eleminate such problems, because FAT32 is supported on all phones.
Try partitioning on pc using:

Regarding Turbo Boost: just put zip file on your SD card, install it through TWRP and follow on screen instructions... :fingers-crossed:
