Latest "wheezy" ISO image (debian testing)

[Øyvind Lode]

Hi:

I downloaded the latest wheezy iso image (business card).
It booted up with speech (software) just fine.
Installation went smoothly until installing GRUB boot loader.
Installation fails at this point.
I only get:
An installation step failed: install grub boot loader to harddisk

This is the last step of the installation.

Anyone else tried the latest wheezy image?
Any ideas?
