I'm back on my old system and have given up on installing at this time. Here are a few more details:
I'm installing from a USB flash drive. The ISO checked out OK with a MD5sum check. I used my 12.04 install to create the bootable usb. I'm installing onto a SSD for / and using my existing HDD for /home. I have the HDD partitioned with a separate home directory.
My first attempts to install I had SATA set up a ACHI. But after two failures moved back to regular ATA. Nothing helped in that regard.
The failure point was when the installer is at the "Removing Extra Packages" point.
I may try to rebuild the USB flash drive; but for now I've run out of time.
