Upgrading to Windows 10

After upgrading to Windows 10 my laptop will not boot up. It goes to the lenovo screen then goes black and over and over again. I decided to wait for it one day. I turned it on and left it on in the morning. When I came home from work it was still doing it. Microsoft can't reset it without an external device.

Re: Upgrading to Windows 10

Welcome to the forums Kr!


Are you able to use the Lenovo One-Key recovery? 


Try taking out the battery and unplugging the adapter and press and hold the power button for 10 seconds. Do that 3 times and then plug in just the ac adapter, (not the battery) and see if it boots up.


Let us know how you get on.
