Booting problems in Vista and Windows 7

I am using a multi-boot manager ( Acronis OSS ) to boot into Windows Vista.

When I choose the boot option which makes my Windows 7 partition the Active partition, the boot lands me in Windows Vista. When I try BCDEdit from Windows Vista the default BCD store is pointing to my Windows 7 partition instead of my own Windows Vista.

Does anyone know what is happening and how to correct this ?

I really want to boot into Windows 7 when my Windows 7 partition is made the Acive partition, and boot into Windows Vista when my Windows Vista partition is the Active partition. As it is I can not boot into Windows 7 although I have a perfectly valid partition already setup for it.

I know Microsoft's Windows Boot Manager is doing somethign I do not understand. But how to correct it via BCDEdit baffles me. Any help would be appreciated.
