Public bug reported:
The starting geometry of my drive was:

The computer is a Dell Precision M6300 laptop. The drive had the Dell
"electronic break the seal" partition, a 60GB install of Windows XP SP3
32-bit with the remainder of the 320GB being taken up by a working
Ubuntu Karmic install.
I booted off the Maverick desktop 32-bit CD and selected "install". When
I came to the partitioning dialogue I indicated that I wanted to install
Ubuntu alongside other operating system(s). It displayed a 2 partitions
(Karmic and the proposed Maverick install) and stated that there were 3
smaller partitions hidden. This seemed right. I clicked "Use whole
partition" (not "use whole disk") then proceeded.
After the installed finished Mavarick booted fine but the Windows and
Dell partitions were missing and there was no GrUB menu. I repartitioned
the disc manually with fdisk so I could restore my backup and my Windows
partition mounted with files in it so it appears that an incorrect
partition table was written without sda1 and sda2 in it but the area of
the disc wasn't reused.
Fortunately, I had a backup...
