ParrotSec was installed on this machine and it was running fine - meanwhile I could not reach it from Grub2 because if I chose MacOSX-32bit/MacOSX-64bit it popped back a Kernel Panic.
On the other hand MacOSX was on the machine - and it can be reached from:
Option key - Choosing HDD as boot from Apple boot menu /// And it was run smoothly
This is why I reinstalled OSX and now Parrot is become unreachable. The Grub options to run Parrot is not showing, only MacOSX.

If I start ParrotSec-boot with AdvancedOptions/RescueMode/ReinstallGrubBootloader, it will exit with "unable to install Grub" both onto EFI and Disk5.
So make this clear ParrotSec and OSX are on the computer but I could not reach ParrotSec because OSX bootloader probably overrode Grub. How can I get back both ParrotSec and MacOSX?
