Receive Fatal Error - Can't Install Grub to (hd0,8)

Welcome to Mint ykaeric
It's good for you that it works. However you can have an almost infinite number of logical partitions in an extended partition. You can only have four primary partitions including the extended one.
I think it's the Acronis bootmanager that has some objection
Don't know how it works, but I use Acronis for backup and think they have good products
