This might lead you to your problem, it's not a definate, but worth trying!

As hexadecimal suggests, it may be worth re-writting the Master Boot Record (MBR).

Do let us know how you get on, one way or the other. It would be useful to make a note of the steps you've followed so you can post detailed information and as a reference for yourself.


Tip Try to be methodical in your approach. Create a check list and cross them off as you go.

Good luck.
