Faulty installation - manual grub needed to boot (Edgy beta daily build 16 Oct)

I have a brand new Intel Core 2 Duo computer and wanted to do a dual boot install of Windows XP and Ubuntu Edgy.

Followed the instructions at https://help.ubuntu.com/community/WindowsDualBoot

Installed Win XP (created a 30 Gb partition for this, left the rest of the disk unpartitioned)

Retrieved and burned a CD image from http://cdimage.ubuntulinux.org/daily-live/ (16 Oct)

Ran live CD, installed (created a 30 Gb partition for ubuntu, 4 gb swap, and 200+ FAT32 for shared files with Windows etc)

Installer completed, but when the system reboots and Grub starts, selecting ubuntu yields 'Error 17: Cannot mount selected partition'

to get the system booted; (boots incompletely - possibly a second bug - TBC)
