Drive C is a partition on a physical drive. Now, when you try to install Windows, does it show the physical drive (Like Disk 0)? If it does, you should be able to delete/create partitions on it. That partition would become Drive C which you should be able to format and instal Windows on.
If that disc does not appear or you are unable to create a partition (Drive C) or format and install Windows on it, there likely to be a hardware problem.
and also there are drives that i dont know appear like a drive 120 MB and other unlocated 43 GB which i cannot use as when i click " new " using these space an error appears , i dont know exactly what is letterly says but generaly i couldn't use it
