have you tried to create a FAT32 empty partition while in xp (using partitionMagic or some other app) and then install mdk on it?
linux doesn't like ntfs file system very much, it can create problems while installing - creating a FAT32 partition, which will later be re-partitioned (to /,swap, /home and all other linux part. you want) by mdk's internal partitioner/mounter resolves this problem
