Hello, I'm facing issue with my laptop's BIOS.

It's Dell Inspiron 3511.  Suddenly when I power on it. It started showing that BIOS is corrupted and Auto BIOS recovery is triggered. 

Then it starts recovery. It easily reaches the point where it shows BIOS recovery is successful and it's going to restart.

But unfortunately after restart it returns to same problem of corrupted BIOS and that loop is going on. 

How to fix this ?? What if BIOS recovery is missing in HDD .How to recover using USB?
