So recently my windows 8.1 lenovo G500 laptop was working really slowly, so i decided to restart the pc to see if that helped. But when I restarted it wouldn't boot anymore!
Basically when i try to boot normally it either comes up with automatic repair and then has the loading screen for a long time and then just a blank screen forever, or it will have the loading screen and then come up with the blue screen with a sad smiley face and say that it needs to reboot, and then when it reboots it does the loading screen and then blank screen forever.
I have one touch recovery, which i have tried, but its not working. I can get into the first screen, but when i go to recovery system is says loading files and then goes to a blank screen forever again.
I have loaded a live version of ubuntu onto a pen drive and recovered all of my files that way.
So now I need to figure out how to either fix it so it boots again, or wipe it back to factory settings.
So my question is, does anyone know how i can figure out what has gone wrong so i can try and fix it through ubuntu, or does anyone know how i can get it to revert to factory settings when the recovery system doesn't seem to be working?
Also note, the laptop did not come with a software cd or reinstallation cd, and I don't know what has happened to the recovery pen drive that had been made of the pc. So If you know a way to make it revert to factory settings it would need to be something that can be done without those things, or have a way for me to create a new back up file through ubuntu first.
Ps. I know almost nothing about the workings of pc software/hardware etc, ive only got this far because of google
please be gentel, and step by step in laymans terms please
Thanks in advance for any help or solutions you can give.
