The first window of a Recommended Installation asks where on the hard drive you would like to install Linux-Mandrake.

The first option is to "Use existing partition" -- This is for when Linux partitions already exist on a drive, such as from a previous installation or as a result of using third-party partitioning software such as Partition Magic.

So if partitions have already been created, you can select "Use existing partition" to manually assign Linux mount points as seen on the next page.
