Since I installed Win2008 I can no longer boot into Win2003

[BigDaddy]

Today I thought I would try Win2008 and created a 15GB partition. And then installed it on this partition. But when I try to boot the old Win2003 by selecting previous windows install in BCD I receive

c:\ntoskrnl is damaged or not found.

How can I fix this?
