Dualboot w/XP32 issue with NTOSKRNL not being found

I have successfully (?) installed Vista 64 on a partition #3. I have
completed the installation process, seen the "semi transparent windows" etc
but when I try to reboot into Vista 64 I receive an error that <windows
root>\system32\ntoskrnl is not found. It's there. In fact ntoskrnl.exe is
in a number of different places in that partition.

The other boot partitions I have are a small DOS boot partition (don't
laugh, I have good reason for it), XP 32 for every day use, and an XP 32 for
"just in case my normal has problems. The other partitions boot just fine -
just not the V64 one.

My boot.ini is:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="XP NORMAL" /fastdetect
/NoExecute=OptIn
multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Vista " /fastdetect
multi(0)disk(0)rdisk(0)partition(4)\WINDOWS="XP LIGHT" /fastdetect
c:\="MS-DOS"

Any guesses how to avoid/correct this error.?
