restore only system state from complete backup

Hi,

I'm going to test a restore from a complete backup of my Windows server 2008 with Symantec backupexec 2012 from a tape drive.

I boot on the disaster recovery cd

I install the RAID driver

I load the recovery file *.DR

If I want restore the entire computer, the restore works !! no problem

My question :

Is it possible to restore only the system state from a complete backup ?

When I load the recovery file *.DR , I see my partition (C: system, D: data) and the system state but I can't uncheck the partition for only restore for example the system state.

The option "recovery the entire computer" is unchecked yet...

Thanks
