Also you can try loading your vista disc and formatting the partition that way. This is a continual problem, but each solution seems to be different. I have a few specs of comps which have created this problem and I will be using a VM to try and re-create the issues, but so far no luck.
Another options is using fdisk on a floppy and seeing if it can detect your partitions.
