I've run into this issue as well when installing Precise on my brother's and cousin's machines, with both the manual partitioner and when simply picking the automatic "side-by-side" option from the installer. The workaround was to always use the manual partitioner to switch the default device for bootloader installation to /dev/sda, after which the installation proceeds successfully.
