Hi, Im running Vista home premium 32 bit and XP pro, dual boot on 2 hard drives and I have tried to upgrade Vista home to Vista ultimate. About half way through the process i get an error that the upgrade could not complete as windows could not update the boot configuration. I had previously used easybcd on the XP drive to fix the problems with dual boot and im sure that this is the culprit. Has anyone else had this problem and been able to fix it?
