I am! But i must confess, my windows 7 installation is on a PATA disk. I have one PATA for Win 7 and three SATA for respectively Lion 10.7, my time machine for both my AMD and my Atom netbook (which backs up to it via network) and a big NTFS 1.5TB for general storage.

I think that your problem is indeed related with Bcd, and the mess happened when you installed Snow Leopard: i think you forgot to disconnect your Windows disk when you first installed Snow Leo, and now the old bootloader survives in your Windows HD, and it doesn't matter how many times you reformat your OSX disk.

My best advice would be, if you have all your data securely backed up, to erase windows, reinstall it (remember to disconnect the OSX disk, if it still there) and then disconnect the Windows disk and install Lion with the latest chameleon.
