My Suse 10.2 used to come up with two boot options. No problem.

Now it offers me several:-
openSUSE 10.2
openSUSE 10.2 -
Failsafe - openSUSE 10.2 -
Failsafe - openSUSE 10.2

The second one is highlighted, and if I just let it run I get the message:-

Error 15: File not found, Press any key to continue...

If I select the topmost option Suse runs up apparently normally.

Where have all these options come from, what do they mean, and how can I correct or delete those that are not needed please?
