Check Fedora Bug #489148
https://bugzilla.redhat.com/show_bug.cgi?id=489148
Particularly the 'issues' part at the end of Comment #7
It seems like Anaconda does not use the partition information 'on disk'
when trying to do an update. It is much more comfortable wiping the
user's disk and doing a virgin install..
Bug above is directed to systems with motherboard raid hardware, but
your note seems to indicate the problem might not be restricted to RAID.

Over the last week or so I've had good luck with pxeboot rawhide
installs using custom disk layouts. But yesterday I changed my office
machine to an MSI P43 NEO3 and Anaconda was stumped.
Different versions of fdisk showed slightly different partitions.
After several attempts to install Rawhide, I gave up and installed
OpenSUSE, which installed without complaint. But Rawhide
still couldn't hack custom layout.
I tried reverting to the "last known good" Rawhide from last year
(anaconds 11.5.0.17) but custom layout still got an unhandled exception.
Finally I swapped hard drives and used Win XP to clear partitions
and install Windows on a 50G partition. The current Rawhide was
able to install using the "replace linux" option.
I know the details here are rather sketchy. I suspect the problem
may be related to the motherboard and the apparent presence of
two partition tables on the same drive. And the problem <so far>
is appearing only on this motherboard.
