boot – my win10 crashed so i want to install ubuntu instead and running into several problems

my win10 crashed (unmountable boot volume error), so I brutally shut it down, and tried to install ubuntu instead of my win 10 (I do not any back up, just erase and install ubuntu). I downloaded ubuntu iso and created a flash bootable USB from my mac using Etcher.
All goes great, till it got stuck in installation with the error: input/output error during read on /dev/sda

from googling around, i understood that my windows is still hibernating and not completely shut-down and this might be the reason for this error. I just want to format this hd and install ubuntu from scratch. is there a way to do it?
