I want to sell my old laptop, but it can't be reset. First I deleted everything and then I wanted to reset it, but I can't do that now.
I always do it that way and it has always worked so far.
What could be the reason? What could be the problem?
Maybe this will help you
Make a USB stick and boot from the and erase entire hard drive and reinstall.
Your korrywurst 😎
And why don't you reinstall Windows?
