I Have a CPU it was Windows 7 Home Premium installed , i Got windows 8 downloaded from Microsoft . I installed it without a CD . I Extracted the .iso file and Just Click Setup.exe , it was really slow so i left it at my house , when i ome Home it enters windows 8 Home Screen . I am really confused , i thinks its gonna ask me Custom or Upgrade but when I'm home it just ask me what color do you want for your theme . I Inserted the windows 7 CD and Installed on drive B: ( B is a hard disk i made with diskmngmnt.exe ) and it boots to windows 7 , i want to shut down my CPU . I turned it back On ( Restart ) and it just shows me a black screen . Any help Please ?? ASAP

oh man... tell me why did you really install window 7 ? windows 8 installation was completed and it was just asking how to personalize... try startup repair with your win7 DVD(do it 3-4 times separately, with a restart between each repair time )... and also boot into windows 8 and turn off fast startup.
hope it helps.

Welcome to EightForums.

Have you tried a clean install.
You will need to reinstall all your programs in Windows 8.

Upgrade to Windows 8 with only a product key - Microsoft Windows

Microsoft said:
Make sure you’re on the PC you want to upgrade. This must be a PC that is currently running Windows 7, Windows Vista, Windows XP with Service Pack 3 (SP3), Windows 8 Release Preview, Windows 8 Consumer Preview, or Windows Developer Preview. (Windows 8 Setup checks that your PC meets all system requirements before it installs Windows 8.)

Have your product key handy. You can find it in your online order information, in the confirmation email for your purchase, or on the packaging. The product key will look something like this:
XXXXX- XXXXX- XXXXX- XXXXX- XXXXX

Make a backup of everything you want to keep. Save it somewhere you can get to it later, like an external drive or a DVD.

Always better to do a clean install.
