I was trying to solve this and i used partimage to restore the MBR from a file. It completely wrecked my partitions. I now have 3, a 100mb, a large one and a 9mb. Windows XP complained and Windows 7 got an error trying to format on the middle drive. I then tried to install on the middle drive and it didnt allow me.
I cant install an os! how do i fix this?!
-edit-
I tried
bootrec /fixmbr
bootrec /fixboot
and
bootsect nt60 ALL /force
no luck, i still cant repartition it.
