Can Windows 7 Support 4Tb Hard Drive?
Contents

Windows 7 supports 2+TB drives just fine, they just have to use GPT and not MBR due to MBR being limited to 2TB partitions. Same for if you wanted to use the drive as a boot drive, you would absolutely HAVE to use GPT and be on a UEFI system (which you are with that z87 board).

How do I install Windows 7 on a 4TB hard drive?

You will need a motherboard that support UEFI! If you already have such a motherboard, then Windows OS must be 64-bit in order to be successfully installed on the 4 TB HDD (regardless of the OS version itself). Finally, you must start Windows setup in UEFI mode.
