Thank you for your reply.
I have a few followup questions based on your response:
Method 1: SBUU 5.5 does not specifically say it is compliant with Windows Small Business Server 2003 (only Windows Server 2003) - I have tried using version 5.2 but it just kept ejecting my CD when asking for 2003 disk. Will 5.5 accept my disk. My software box says "Win SBS Std 2003 R2 English 1 pk DSP OEI CD 1-2CPU 5CLT w/WinSvrSP2" this seems like it meets your criteria.
Method 2: Would the missing RAID drivers cause the error "NTLDR is missing" when booting from the 2003 CD?
