MINIX needs one primary partition of $TOTALMB MB for a full install,

If there is no free space on your disk then you have to choose an option:
   (1) Delete one or more partitions
   (2) Allocate an existing partition to MINIX 3
   (3) Exit setup and shrink a partition using a different OS

To make this partition you will be put in the editor \"part\".  Follow the
advice under the '!' key to make a new partition of type MINIX.  Do not
touch an existing partition unless you know precisely what you are doing!
