Netweaver Server restore

Hi ,

unfortunately my netweaver server box OS got corrupted , i am not able to start it with Operating system .

Server details are as :--

OS : Windows 2003

DB: MS SQL 2005

SAP: Netweaver 7.0

I reinstall OS windows 2003 on another Drive without formatting any data. Now , i am able to boot server and see all old data (USR folder, 3 db files , log files etc)on server.please help me out with some details so that i may restore Netweaver with available data. i have 10days back database backup which was created on MS SQL console not by SAP TC.

thanks
