That is basically correct, you can't remove the root partition, while it
is in use....

What you could do though, depending on how big that boot partition is,
is copy the live CD to the boot partition, set a boot option to boot
that as the root, and then do your normal install in the main big
partition.....

I've never done, or tried this, but it should work....The minimal
install cd is ~50MB I think....

All that said, I'm an LVM guy myself, and like to have a few partitions
about for different things depensding on the machines usage. :)
