I was installing Ubuntu 12.10 from a Pen drive on Sony Vaio(Model is: SVE151D11L. 64 bit i3 processor) using an ISO image. I made the pendrive bootable by using "Universal USB Installer". The System starts booting from the pendrive but it gets stuck on the UBUNTU start screen(the one with dots).
On Pressing ESC at that screen, It shows:
Buffer I/O error on device sr0, logical block 0
Buffer I/O error on device sr0, logical block 1
...
I've been trying for hours, tried installing 13.04 instead, the same problem occurred again.
Please Help me out.
EDIT
I opened it in another computer the pen drive worked fine.
