How to use more than 2TB on a hard disk drive in Microsoft Windows 64bit (convert to GUID GPT)

This video will show you how to fix this issue:
Virtual Disk Manager
Only the first 2TB are usable on large MBR disks. Cannot create partitions beyond the 2TB mark, nor convert the disk to dynamic.
When Microsoft Windows formats, partitions, and prepares a hard disk drive for installation of the Microsoft Windows operating system, it tends to favour the MBR partition table format. The problem with the MBR partition table is that it supports up to a maximum of 2TB usable storage space, regardless of the way the user tries to create, partition, extend, or divvy up the volumes on said HDD. Any remaining storage space after the 2TB mark is unusable and is essentially wasted under the MBR partition table.
If you want to use more than 2TB of hard disk drive storage space on any given harddisk, you have to convert your MBR partition table harddrive to GUID Partition Table (GPT). The problem is that not all motherboards and BIOS combinations support GUID Partition Table (GPT). In order to convert an MBR partition table HDD to a GUID Partition Table (GPT) HDD, all content stored on the HDD under the MBR partition table will be lost (it will be deleted). This is why before performing this task, the user should back up any irrecoverable data to another storage medium (such as USB flash key, DVD writable disc, cloud storage, etc).
Furthermore, if after converting your HDD from the MBR partition table to the GUID Partition Table (GPT), you wish to install (and be able to boot) the Microsoft Windows operating system from said GUID Partition Table (GPT) HDD, your motherboard must also support the EFI System Partition. If your motherboard ONLY supports the GUID Partition Table (GPT) and not the EFI System Partition, you will still be able to format the drive to the GUID Partition Table (GPT) system, but you will not be able to install and house the Microsoft Windows operating system to this disk. You will be able to use this GUID Partition Table (GPT) hard drive as a secondary or slave hard drive for additional storage space, with another physical MBR partition table hard drive (any size amounting to or under 2TB) housing and booting the Microsoft Windows operating system as the master hard drive.
The method shown in this video can be done using simply a 64 bit version of the Windows operating system (so no additional software needed), HOWEVER in order to do so you will also need either access to ANOTHER computer that has a 64 bit version of Windows installed that supports GUID Partition Table (GPT), OR you will have to install your 64 bit Windows operating system temporarily to ANOTHER hard disk drive in order to perform this conversion (this installation of Windows can be temporary and therefore does not have to be connected to the internet, nor activated with Microsoft.)
This method should theoretically work with any 64bit version of Windows, so Windows 10 64bit, Windows 8.1 64bit, Windows 8 64bit, Windows 7 64bit, and Windows Vista 64bit.
Under Disk Management in Windows, if the Convert to GPT Disk option is faded (greyed out) and inaccessible (Unallocated space with no option for New Simple Volume, New Spanned Volume nor New Striped Volume), you need to make this hard disk drive temporarily a slave hard disk drive (secondary HDD) to another hard drive that will boot up a 64 bit version of Windows (this can be a temporarily installed, unactivated version of Windows 64bit). When booting Windows 64bit from the HDD that is not the target hard drive to be converted, under Disk Management, identify the slave hard drive to be converted, then starting from the right and moving left, right-click on each volume on the target hard drive and select Delete Volume. Do this until all active partitions on the disk have been deleted and you are left with only one or more volumes of unallocated space on the disk. From there, again under Disk Management, right click on the drive identifier and select Convert to GPT Disk.
This video will also show you how to enable the GUID Partition Table (GPT) and the EFI System Partition on an Asus Strix Z270F Gaming ACPI BIOS under the Boot\CSM (Compatibility Support Module) function, switching from the Legacy OPROM to the UEFI Driver (skip ahead or fast forward to 13:00 to find out how).
