PC Tablet is not booting properly

Hi all,
I am new to this forum. I have a Wespro Tablet Pc 7 - K-786. When I try to boot it, I am getting a black & white bars after which "system is demaged please try to recover from external storage". Is it possible for me to recover my tablet from this? Since I am a novice in this area, if you provide detailed steps it will be useful.
Thank you in advance
