AFAIK you can install the windows-8 within the windows-7. Because I have installed Windows-7 within Windows XP it was working like a charm. Just you have to make sure your system drive I mean be sure on which partition you have to install the windows-8. If there is same size partition then you can change the size of partition to recognize the difference between them.

I think it's possible. Because some guy had installed WIN8 on other disk, so there are dual system on the computer. Just try but as far as I know, it will be much trouble if you want to remove Win8 from your computer without affecting WIN7. Not sure

I didn't find a way to do so… At least I didn't want to risk a working Windows 7 system.

When you run Windows 8 setup from other version of Windows, there are three options:

  • Save Windows parameters, personal files and applications
  • Save only my personal files
  • Save nothing

The first two options really mean upgrade. I wasn't sure enough to try the third option. I understand the third option is to replace the existing OS with the newly installed Windows 8.

I tried to find information on the Internet about it but I wasn't much successful. However, one of the step-by-step guides, clearly mentioned:

You have to boot from Windows 8 DVD or USB to perform a clean boot.

That's what I did. I installed it on the 2nd partition of the hard drive, and it gives me the option to boot to Windows 8 or the previous version of Windows.
