Windows installation was not successful. Your previous version of Windows is being restored. Do not restart your computer during this time.     I have a small Toshiba laptop that has Windows 7 installed.  I have uninstalled my Norton (as I was instructed to do by a friend); tried to install Windows 8 again; and got the same message.  Any suggestions???

Hi Dreah117,

Thank you for choosing Windows 8!

 

I understand you get this error on trying to upgrade to Windows 8. Its good that
you removed your anti virus software are there is a possiblity of it
causing issues with the installation

 

I have some questions regarding your system

1. Which operating system (OS) are you upgrading from?
2. Is it a 32 or 64 bit OS ?
3. Are you trying to install a 32 or 64 bit Windows 8?

 

You can try these methods to see if it resolves the issue

 

Method 1:
Run the Upgrade Assistant and check to see if your system meets the minimum requuirements.

b) Hover the mouse over it to verify the name

c) Right click on the icon and select "Exit/Disable" or a similar option.

 

Method 3:
Make sure your computer is updated through Windows Update.
