windows 8.1 update failed error 0xc1900101-0x2000c

I wanted to update my win8 to win8.1 but the installation fails and gives me error 0xc1900101-0x2000c. I searched a lot about this but I only got answers for error 0xC1900101 - 0x40017 but that too is not helpful. (HP Pavilion G6-2312AX AMD A10-4600M APU. 2.30 GHz & 4GB RAM) Need Help for the fix. Thank You
