I tried 5 of 6 and 6 of 6 with the same result.
I have 2 disks, one sata and one usb, the sata had existing LVM partitions (sda5) and the usb had 3 normal partitions.
Attempting to remove these partitions several different ways from the partitioning dialog kept throwing "An error has occurred" message (or something like that), and restarts the install in text mode.
Same thing happened when I tried to generate a new partition table to either disk.
I ended up Using Ctrl-Alt-F<something> to get a console and using fdisk to re-write an empty partition table to both drives.


Reproducible: Always

Steps to Reproduce:
1. Start with existing LVM partitions and 2 disks (maybe 2 disks not needed)
2. Try delete partitions in install partitioning menu
3. 


Expected Results:  
Partitions should have been deleted allowing me to create a fresh partitioning scheme.

Major only because it's in the installer.
