first i want to thank you for this great cd

i used mbrwork to repair mbr on my hard drive
i've reset mbr to zero then i used the option to restore MS partitions which works fine
however now i want to restore linux (ext3 and swap) partitions to the mbr,
i got 2 windows partitions which was restored by mbrwork
and 2 linux partitions SWAP and ext3 which are missing on the mbr
