Hi, I've encountered a very similar problem, but in the stable (wheezy) release (installer build 20130613). I'm not even able to go through the iso-scan step, so I consider the severity to be a "little bit" higher than normal, as I'm effectively unable to install the stable version of Debian by the "boot from hard drive" method.
The steps to reproduce the problem on my machine are as follows: (replace /dev/sda3 and (hd0,2) with paths to a free, bootable >1 GB partition) wget http://ftp.debian.org/debian/dists/wheezy/main/installer-i386/current/images/hd-media/boot.img.gz wget http://cdimage.debian.org/debian-cd/7.1.0/i386/iso-cd/debian-7.1.0-i386-netinst.iso gunzip -c boot.img.gz > /dev/sda3 mount /dev/sda3 /mnt/bootdisk cp debian-7.1.0-i386-netinst.iso /mnt/bootdisk/ umount /mnt/bootdisk shutdown -r now Next, using grub, boot to the installer: root (hd0,2) chainloader +1 boot First problem: As was reported before, the installer fails to find the iso image. The image was copied to the partition containing the installer, just as I was told by the last paragraph of http://www.debian.org/releases/stable/i386/ch04s03.html.en. I noticed that there are no sd* or hd* files in the /dev directory (on a computer with 2 PATA hard drives), so in my case, something went obviously wrong in hardware detection, causing the search to fail. Log does not seem to be very useful -- however, there appears to be an issue with modprobe: ...

Second problem: The first problem can be simply solved by using a USB flash drive containing the iso image. The flash drive is correctly detected and the image found, yet the installer fails again with basically the same (general) message. Debug log shows that the image was indeed correctly detected, so I suppose the modprobe issue must be the cause of all problems: ...

As I'm not even able to start the installation process, I cannot comment on the other two issues reported. Thanks, Martin Pavelek
