Windows 10.04 and Windows are used for laptops. But a few days ago, Windows 7 suddenly had a blue screen and crashed. More importantly, the background turned black and asked for activation. The blue screen may be because the video card is too hot and there is no way to use the black screen. After all the methods have been used to reactivate the video, the system decided to reinstall xp.

Update-grub

In this way, the newly installed Windows operating system can be displayed in the Grub menu that is started upon startup.
