I bought a PC from a shop a few years ago, it came with the usual pre installed windows etc, but here'smy predicament. I have upgraded my OS and put Windows 7 ultimate on my PC and as such I have formated my HDD. Even though I have formated my HDD I still get a black screen flash up telling my the make of my PC, which was an E System. Not just that but my PC HDD currently has 75GB in total free that I can ue but when I boot my PC up the black screen that pops up, which incidently is the same screen that tells you to press any key to boot from CD, it says that the HDD has a capacity of 82GB. I presume that is where the message telling me the make of my PC is comming from as I have formated my HDD, but what I want to know is how can I get full use of all of my HDD? I should also point out that this space doesn't show up as a partition, the only reason I know it's there is because I get told the make of my PC as well as a message saying my HDD is 82GB?
