Not threats after scan but Boot record 2

Using Norton Internet Security 2005 on Windows XP.

 

Had a virus about a month ago show up. It quarantined it.

scans afterwards were clear.

 

Not having any pc problems.  Installed the latest update today - Scanned computer.

Scan came back "No Threats Found" but Under Master Boot Record it says 1 and under Boot Record it says 2?

 

Should I be concerned about the 1 and 2 under the Boot Records? I couldn't find an answer online as to what this really means. My next step should be??..........

 

Thanks.
