My previous email should have read, 'I can only access my computer by
booting from the Ubuntu Cd and running - Try Ubuntu', and not 'I can not
only'.

As there does not appear to be a solution to the problem, how do I
un-install Ubuntu and return to Windows 7? The re-install program has no
provision for this.
