debian-installer: Lenny fails to install on system with USB and SATA disks

I finally found a bug associated to my initial post:

[Boot order / Grub / USB installer]
http://lists.debian.org/debian-user/2010/06/msg00308.html

I believe this is related to:

Hopefully this will be solved for squeeze !

Boot Debian from an USB device

I have been struggling for the past days to prepare a USB Key for booting up debian. I was reading:

http://d-i.alioth.debian.org/manual/en.i386/ch04s03.html#ftn.id318505

Well the important part is :

# zcat boot.img.gz > /dev/sdX

This is completely different from:

# zcat boot.img.gz > /dev/sdX1

One is writing to the disk (create the partition at the time), while the other one is simply copying to the 1st partition.

BTW, there is also a good link that never showed up on my google search:
