There is nothing to worry about it. Get a Disc of Windows 7 and insert in DVD-ROM and restart your system. If it boots it automatically then it will show a black screen with a blinking cursor asking "Press any key". Otherwise you will have to boot it through boor menu of your computer. While booting it will ask you where to install the Windows. You need to just choose the partition and do not forget to format the drive before installation. You will find format drive option in Drive Options. After that it will install Windows in that partition.
