Attached. Also boot.ini.
Not included here, but earlier I thought the partition(2) might be a problem, so I also tried replacing boot.ini with the attached boot.ini.change, and not including the utility partition in the conversion. No joy.
To recap:
Dell box, ide disk(0) has dell utility partition, partition 2 bootable to XP Pro.
Added second disk, installed Win 7 Ent on that disk for dual boot.
Bootscreen now goes to BCD, not boot.ini (i.e. choices are now "Older Windows" and "Windows 7")
Booting into XP to run converter on running machine.
