Installing Windows 10 Pro X64 on 3TB Hard Drive
I recently purchased a internal 3.5 inch SATA Seagate 3TB Hard Drive from Amazon as it caught my eye because it was on sale. I'm trying to install Windows 10 64 bit, and my problem is that my desktop, a Dell OptiPlex 3010, is only seeing 2.7 TB (2,794GB under DiskPart) of the new drive, instead of all 3TB or something close like 2.9TB. The BIOS is seeing the entire 3.0 TB. That's several hundred gigabytes the OS is not seeing. I've done a lot of Google searches, and most are the steps I've tried with no success. I've changed the boot mode from Legacy, to UFEI and disabled secure boot in the BIOS, and I have done a BIOS update. I used Rufus to create a UFEI GPT bootable Windows 10 flash drive from the ISO. I know that I may not need a massive 3TB boot partition, but it would be nice to squeeze what I can out. My ultimate goal for this machine is to be a media center, hence the big hard drive.
