F19 install and custom / RAID partitioning

[Gary Stainburn]

If I do not create the biosboot partition I can create everything else without 
errors but when I return to the main screen I get an warning that there is an 
error checking the storage configuration. The error is:

you have not created a bootloader stage 1 target device

This was the error that I google'd and got the instruction to create the 
biosboot partition at 1MB

catch 22
