Digital Dark Age was right...if it doesnt boot after you merge it, reboot back into vista and install acronis and set the big new mac partion drive to "active". That fixed it for me....for me..i have a 250 hfs drive partion and then i also added a 250 ntfs drive=500
he also suggested to do this....... "run fsck -y in single user mode as there might be some disk errors. "
my question is still, do i need acronis? I am surprised the vista dsk mangement wouldnt do it. anyways
Just use diskpart.exe in Vista to set the partition to active. Done.
