OK so I would like to upgrade an old 500GB SATA HDD on this old mini PC. I want to install a 4TB SATA HDD but the BIOS (MegaTrend) only sees it as a 1.8TB. Can I install Windows 7 Pro on this drive using MBR partitioning the drive into two partitions ? Will Windows 7 allow me to create two partitions so that I can make use of the entire drive ?
