How to install Windows on a 4TB HDD without losing 2TB from it being in MBR?

[relindwto6]

I'm trying to install Windows 10 onto a 4TB harddrive by plugging it into my computer, moving the Win10 ISO files onto the drive, then activating it in DiskPart. However, I am unable to activate the partition unless the drive is in MBR format, but if I do that, 2TB of the HDD becomes unusable when you get Windows working on it.

Is there a way to install Win10 on a 4TB HDD, without converting to MBR and losing 2 TB of storage?

You could partition the drive...or See Here..l.

Note : There is always a risk of data loss...

To install Windows onto a drive of larger than 2TB the drive needs to be partitioned as GPT first then have the partition made as NTFS 4 TB.

Begs the question why you are installing from the drive you are using for windows. The normal way is either from DVD or a pendrive. The reason to use this method is Windows 10 needs more than 1 partition to boot and the install knows how to partition your 4TB as GPT.
