How Can I Use 4TB on Dell Poweredge 840, Help

I want to use all 4TB of my Windows Server 2008 R2-running Dell PowerEdge 840 server. However, the MBR in the BIOS only allows me to use 2TB of it. Is there a way to get around this?

If the MBR on your BIOS limits you to 2TB, you can try to put this concern to rest by converting your MBR to GPT. GPT partition style allows you to use disks larger than 2TB on Windows and create numerous logical partitions.
