Cannot Boot into Vista, Need Help!

I REALLY need help!!!!!I think I just blew up Vista. I changed the EasyBCD configurations according to these instructions (or so I thought). When I rebooted, I still got the GRUB boot screen and then it went to the Vista Boot Loader and I chose Vista on both. When I selected Vista on the Vista Boot Loader it brought up an back error page that said something might have changed in order to cause the issue. It gave a file in part of the error and I think it was something like c:, I can't remember the path but the end I think was Windows loader or boot loader. I cannot currently boot my Vista HDD. I can boot into Feisty but I don't have wireless configured yet. How do I get Vista back to being bootable and use the Vista boot loader to start Ubuntu? Thanks
