I added a small EXT4 partition, tagged it "bios_grub" & ran the Ubuntu Desktop 10.10 install. Using the "specify partitions manually" option, I can specify where to put the boot loader. After the install ran without complaints, I booted up the machine, but the Chamelon boot loader did not offer me a choice of a Linux partition to boot anymore. It did not look like the Grub boot loader got installed properly. I attempted to install it manually again, but I seem to have goofed that up & the Grub loader may have wiped up Chameleon, making it everything inaccessible. At this point I may just start from scratch again.
