Parrot Installer Grub Error

The Parrot Installer fails on the last step ( Install the GRUB Bootloader on a hard disk )
I am running Parrot 3.11 Security x64
I used dd on a Macbook Pro to copy the ISO onto my flash drive
Then I booted into live mode and ran Install Parrot to install Parrot onto another flash drive
It got all the way to the last step, and then it threw an error about GRUB


start the installer from the boot menu, not from the live desktop
