I want to "successfully" reformat & reinstall operating system on a custom built machine. The problem I am having is it is only using 540 mb of the drive when I install instead of the 2.4 gb the drive actually is. I tried another hard drive and it was 6 gb and only loaded 540 mb as well. What do I need to do to get the system to install correctly? I chose yes when the question came up about larger partitions. Please advise. Is there something in the BIOS I'm missing or am I doing something wrong in FDISK.
