I did a screen installation as my last one was faulty. The VAIO didnt have an operating system on it at the time.

Tried to install Win 7 and came up with a file corruption message.

Now, whenever I boot up, I get the Sony Logo ok, but the screen then disoplays this ( see attached pic)

It wont boot up from a CD or DVD when inserted.

How can I fix the BIOS?
