What happens when the screen appears after booting, what should I do?
Usually this situation occurs because the system has not successfully found the system disk and cannot start successfully, so it will stay on this interface.
First of all, we need to press DEL to enter the BIOS, under the Boot option ----- Boot option # 1 ------- select windows boot Manager and press F4 to save and exit, we can return to the windows system to boot.
If the above method still does not allow the computer to return to normal, then we must reinstall the system. If it prompts that the SSD cannot be found during installation, this is a problem with the computer motherboard. Please contact us for after-sales processing.
