Hi Ben,

Thank you for your reply.
So, I am sorry, I forgot to mention it, I followed "4.3.2 The flexible way".

On this page, I followed http://www.debian.org/devel/debian-installer/ :
"The following images are available for squeeze RC1:
* other images (netboot, USB stick, etc) [...] i386"
Which brings me to that URL :

However, I think the wrong choice was to select "netboot" (instead of
"netinst") as shows my reply to your comment below...

Actually, I understood the difference between both methods.
However, I had the impression that the "netboot" image could be used to
set up a very minimalistic system for a network install. And that it
could be done on a USB stick.

I was comforted in my choice when reading the following sentence (in
particular what's between parenthesis):
"Next you should create a syslinux.cfg configuration file, which at a
bare minimum should contain the following two lines (change the name of
the kernel binary to “linux” if you used a netboot image)"

So, I understood I could create a USB stick from a "netboot" image.
I thought it was different from the "netboot" method in the sense, that
imagined the purpose of the "netboot" method was to boot directly from
the BIOS on the network, then to fetch the "netboot" image served by
another computer... Isn't it that way ?

Yes, that's why I wrote "anyway", but I read that "http://kitenet.net/~joey/blog/entry/Debian_USB_install_from_hybrid_iso/";, and I was tempted to try.

Actually, I performed that series of actions:
# mkdosfs /dev/sdX1 
# syslinux /dev/sdX1
Then I copied the following files (with cp -rp) from
http://ftp.nl.debian.org/debian/dists/testing/main/installer-i386/current/images/netboot/gtk/debian-installer/i386/ :
#  install-mbr /dev/sdX

After the kernel panic, I tried with the iso card that I fetched from
here :

I used "cp -rp" to bring it on the stick after the mkdosfs and syslinux.

So, now I understand that I am not allowed to mix the **netboot**
"initrd.gz" with the business-card iso image.

I guess that if I use the "netinst" or "business-card" install, I'll be
able to achieve the installation. I'll make you know.

However, do you really confirm that it's not possible to use the
**netboot** (and not "netinst") image as a minimalistic system to
perform a network installation from a USB stick ? 

Bye, and thank you again,
