Nokia India — Error :-Unable to find a bootable option press any key to shut down on Nokia lumia 625 phone

Address:

Hoshiarpur, Punjab

My phone Nokia lumia 625 was working but got heated up. I presumed it to be a normal .One day suddenly this remark started showing on the screen " unable to find a bootable option press any key to shut down". I took it to the nokia dealer, he in turn sent me to NOKIA CARE. Nokia care just saw the error and surrendered that it cant be done as earlier also customers having this problem were not helped as this error is not solvable.
