Since you are doing manual vs kickstart, you need to do additional steps
Before you go into the disk system in the UI

Control-Alt-F2
fdisk (or gfdisk  or parted depending on your prefs and needs)
clear the disk and set it up how you want it with the types set on each
partition.
go back into the UI and do the things you wanted. have it reread the disks
and have it use the existing partitions versus anything else

Option 2 is to go into the advanced partitioning tool blivet and see if it
can be done through that.. but I think you still need to do a
'slackware/arch' setup first
