So im gonna start this section with some problems that can be common and how to fix them
Basically GRUB is a multi bootloader that allows you to run multiple hard drives at once and helps load multiple operating systems off different hard drives, now an issue that can occur when removing a drive is grub wants to detect a drive that ISNT there.. so all you have to do when you get error 21 is
enter Standard CMOS Setup
set the Primary Master to:
Type = User, Mode = LBA
by scrolling through the options
then set the Primary Slave to:
Type = Auto, Mode = Auto
and problem solved
