If it's Windows 10 we have an exit that usually doesn't involve ordering restore media. We can make a Windows 10 install USB stick. Google "How to use the Microsoft Media Creation Kit."
You'll have the usual work to do after Windows is installed.
If other versions, you may have to order "restore media" from Asus.
Finally, if the HDD has failed, you get to replace that and then repeat the above.
So, I was resetting my ASUS laptop and it froze at 40 percent, then just shut down; it was in charge. Now, every time I switch it on, the ASUS logo appears, then the screen goes grey and then it goes black. This process keeps on happening again and again. I don't know what to do.
