Windows 10 hard reset stuck for 32 hours now on 16%, what are the options??

My Lenovo thinkpad edge e 431 running windows 10 got stuck for in BSOD loop but after I disconnected everything it booted into desktop, so I decided to do factory reset. I choosed option remove all. After 32 hours it's still stuck at 16% of factory reset. On the screen is just Lenovo logo and spinning dots and message about factory reset with percentage. So what are the options?? Should I wait for god knows how long?? I have Windows 8 CD that came with my laptop so should I reboot the laptop and install windows 8??

I have about 2 more days to fix my laptop after that I need to start working again :(
