PC won't boot after lastest Windows 10 update

Your mother board is damaged and you can't just fix it.

The second you turn it on, spam SHIFT+F9 it might work for you, it should eventually take you to the trouble shoot screen, if it works than I recommend clean reinstall of windows, restore point won't work and it's most likely a major windows corruption.

Hey, I don't know if you still have this problem, but when you see the Lenevo boot screen, spam SHIFT+F9 until you reach the trouble shoot screen, then you can restore, or reinstall windows. It might be different for you, but on my custom built by me PC, it worked beautifully. If it doesn't work, I'm so sorry, along with every one else. I'm 16 and this is all I can offer, and Microsoft needs to fix this, I think it happened for me when I tried to install Radeon GPU drivers and windows update at the same time.

Literally NONE of this works on my Wife's Lenovo 720-15. I can't even get into frigging BIOS anymore. I can't roll it back to a save point. It won't repair by itself or from a USB drive version of Win 10 I created. NOTHING. At this point I am taking it to a friend with 30 years of desktop support experience. We can hopefully save her data but it looks like a clean reinstall of W10 is in order...or a bios reflash.

I had the same issue with my Toshiba laptop but managed to resolve it by performing the factory reset i.e. by pressing the zero (0) button while hitting the power button. Keep pressing the zero button until the computer starts. It works for me and I don't lose my data though..
