Laptop won't boot after Creator's Update install

[SDDefiant]

I recently left my Lenovo Y580 (i7-3630qm 8gb GTX 660M) to install the windows Creator's update a few nights ago. I woke up to the laptop in the Lenovo boot recovery screen. Which says my recovery media is not properly formatted.

I figure the update probably botched, tried restarting a few times, keeps placing me back at the Recovery screen. Decide to use my Windows USB Boot drive to repair my PC using startup repair or similar: system restore shows no Windows restore points for me to recover into.

Windows startup repair throws "Startup repair couldn't repair your PC"

I decided to just reset the PC using my recovery drive. I get a "There was an error resetting your PC"

EDIT 1
I also tried to use Windows advanced boot options to get into any of the safe mode boot.. it just puts me on the desktop with no start menu. It's on safe mode, definitely - but it will not respond to Start + R or Ctrl +Alt +Del.

Now, normally I would just reformat the drives, reinstall my stuff and go about my business.. But I don't have a Windows 10 installer, this laptop was a Windows 8 unit originally and I'm worried I'll lose my Windows 10 license if I reformat.

Help greatly appreciated!

Seems the update installation was not successful and somehow it corrupted the recovery drive.... Now reformatting may cause u to loose ur license.... The only option am seeing is taking it to lenovo if its under warranty and ask them to repair it...

From what I understand about windows 10 it's connected to your Microsoft account now because my system crashed because of the update too and when I reinstalled it I just clicked the link that says "I don't have a key" and finished and it says my windows is activated by a key linked to my account.

Thanks for the quick replies!

Sadly this laptop and well past the original warranty and the original warranty period.

I vaguely remember seeing that option somewhere before. Might be worth a shot, yeah.. I'll update regarding what happens if I do decide to do a straight up reformat.

Do you still have your Windows 8 key? Apparently they are still accepting windows 8 keys for windows 10.

It's an OEM key.. So the key should be the sticker attached to the bottom of my laptop, I think

Yeah I think so too. you should be all set then, but if not I have seen others on here post about calling microsoft and they said they were very helpful.

Nowadays, i dont think the oem keys are stickered at the bottom... i highly doubt it.....
Like what jpe1701 said, i just realized that the windows key is actually connected with your microsoft account, so just formatting and logging in will get your license back...

i have the same problem and my solution was done by join in safe mode and uninstall Geforce drivers, after that seems that everything works
