"Then it talls me that fsck.ext2: NULL
SuperBlock could not be read or does not describe a correct ext2 file system Try running e2fsck w another Block."
I do not know exactly what your problem is. I can give you a generalized fix that will probably solve the problem. Try this:
Boot a rescue CD. There should be a rescue CD mode on your Mandrake install CD. Then run fsck against every Linux partition except swap. It is important that you tell fsck the correct file system type for each partition and you can find the file system types in /etc/fstab. So a fsck command would look something like:
fsck -t ext3 /dev/hda1
Answer yes to everything that fsck asks you. After fsck is finished look in each partition's lost+found to see if fsck put any lost files or file fragments in lost+found with a number for a name.
Be prepared. Create a LifeBoat CD.
