Hello there, i also have the same problem. I tried starting my Asus laptop, but it won't go start, when it comes to Repair computer or Start Windows Normally, both are not working. When i press Start Windows Normally, it will restart back to same page where Repair Computer or Start Windows. I tried what you say using F8 and press safe mode but it stuck on Class.PNP, and i have no idea at all what is that. Will anyone help me please? Now im using my other laptop.
