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 which has installed Windows 7.  I uninstalled my Norton (that I was instructed to do so by a friend); tried to reinstall Windows 8; and got the same message.  Any suggestions?

Hi Dreah117,

Thanks for choosing Windows 8!

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

I have a few questions about your system

1. what operating system (OS) you upgrade?
2 what is a 32 or 64 bit OS?
3. you try to install a 32-bit or 64-bit of Windows 8?

You can try these methods to see if it solves the problem

Method 1:
Run the upgrade wizard and check to see if your system is compliant with the minimum requuirements.

Method 2:
Disable or uninstall a software such as CD/DVD burning utility or third-party disk utility to defragment programs such as perfect disk / Daemon Tools

(a) in the notification area, next to the time looking for icons of software disk utility

(b) pass the mouse over it to check 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.

Method 4:

Disconnect all unnecessary external devices such as printers / joysticks etc.

Method 5:
Put the computer to boot is a way to solve problems
