I installed Windows 7 on a new OCZ Vertext 2 SSD drive. A few days later I decided to reinstall Windows 7 again. So I went through the normal installation process, deleted the partitons with the setup program, formated the drive and so on, completed the installation. I rebooted and everything looked okay. I installed some drivers and rebooted again. This time the "old" istallation of Windows appeared with installed programs, desktop backround and all. What did I do wrong?
