I got this laptop for my birthday. And it was in good condition with a branded wallpaper on the main screen and red patterns when loading Windows when you need to enter a password. But since I first dealt with a branded gaming laptop , I installed Windows 10. Then I realized what the problem was and installed again his native Windows 7 Home Premium and activated it. But even after the BIOS update, I still do not have those wallpapers and the red pattern when entering the password. Is there any way restore the 2011 laptop to its original state with all the utilities and wallpaper on the desktop?
