parition become unformatted after retstoring from image

Hello

I have backup image of Vista64 and WinXp. The restore process passes without any errors. However ofter reboot the partition to which I did restore became unformatted. At the same time next partition became active. I also tried to make only one partition and restore to it. Again it became unformatted.

This happens with both of my images.

Please advise what I can do with it.

Thanks a lot,

Anatoliy
