Could not find Primary Partition

I was playing with Partition Magic 6 what I remember is merging my logical drives and while saving it I had an error message which I ignored and quit the program. Restarted my computer it gave me Inaccessible-boot-drive error message…(i’m using window2000 pro) to make the long story short – I can see all the logical drives using bootdisk but there is no primary partition, it is gone… again the logical drives are more than z… tryed to format the hardrive using partition magic again it brings error message 4 and could not save the change. Need help
