Intall Failure - Partitioning fails

[Erik Dykema <ed2019@columbia.edu>]

Hi-
	In the Jan 29th builds, partitioning fails on (at least) two different 
machines, a Dell Powerapp Web 100, and an HP DL 360 G3.
	Installer seems to work fine, then kicks out to the menu with 
'Partition a hard drive' highlighted.  Pressing enter, the screen turns 
blue then returns to the menu.
