How to fix Fatal error during installing Ubuntu, Fix Grub install failed, this is a fatal error.

If someone is new to the Linux platform, GRUB must be a new term for them. GRUB basically means Grand Unified Boot Loader, which is program that calls Linux or Unix operating system into the memory. GRUB is a default Bootloader and Manager for Ubuntu since the launch of Ubuntu v9.10.

Coming to the Fatal error during installing Ubuntu or any other Linux based OS, there are several things that might be causing this error to occur:

1. Secure Boot

Make sure that the secure boot is disabled if possible, because older version of Ubuntu  have issues dealing with secure boot. The easiest way to check if secure boot is disabled or not is by using Windows Powershell. Run the Powershell as Administrator and type "Confirm-SecureBootUEFI". If it returns TRUE, then the secure boot is enabled and if it returns FALSE or "cmdlet not supported", secure boot is disabled.

2. Drive space for Ubuntu/Linux

Make sure that you have shrinked the windows partition properly to allow Ubuntu to be installed alongside windows on the that partition.
