I have made this huge mistake of installing Windows 8 Developer Preview on top Windows 7, with an .exe file. Downloaded from torrent.
It seems it has expired and the system restarts without a prompt every 2 hours.
I have all my files, programs and their paths, savedatas piled up in Drive D, so I'd like to format Drive C, and reinstall Windows 7. I have not made a system restore DVD the first time I opened the PC, back in Win 7. I have a Windows 7 Repair dvd, but it says it's only for Samsung computers, mine's Asus. And I have a 8 GB USB flash.
So can I format Drive C, where Windows 8 is installed on top Windows 7, and restore Windows 7? I have an x64 system, so do you have a verified x64 "Windows 7 boot from USB and install" iso file?
Thanks in advance.
