Error: ELF header smaller than expected in Ubuntu 13.04 64 Bit

[salil2]

I installed Ubuntu 13.04 yesterday on my SONY VAIO Laptop. Third time, when I started it, it showed me the error saying that ELF header smaller than expected.

I ran boot-repair, and the logging data is posted at paste.ubuntu.com/6005483

Really appreciate the help in this regard.
