Hi there,

I am still struggling to create a USB key to install debian. I am following:
http://d-i.alioth.debian.org/manual/en.i386/ch04s03.html#ftn.id318505

Steps:
- Pull in the USB key : SanDisk Corp. SDCZ2 Cruzer Mini Flash Drive (thin)
- Make sure it is not mounted (check status of 'df')
- Check dmesg status and retrieve dev number (/dev/sdb1 in my case)
- Clean partition:
$ sudo mkdosfs /dev/sdb1
- Copy boot.img.gz:
$ wget http://people.debian.org/~joeyh/d-i/images/daily/hd-media/boot.img.gz
$ zcat boot.img.gz > /dev/sdb1
- When command return, check status of disk:
$ sudo cfdisk /dev/sdb1

FATAL ERROR: Bad primary partition 0: Partition begins after end-of-disk

Press any key to exit cfdisk

Could someone please let me know if this ok ?

By the way if I plug/unplug the USB Key, my debian system seems to
recognize the disk anyway:

Thanks for hint. I am just looking for creating a simple USB Key to
install debian on a system without CDROM/DVDROM

That's unnecessary, as your whole disk will be replaced moments after.

You should copy the imagem to the disk, not to a partition:

zcat boot.img.gz > /dev/sdb

You'll probably need to be root to do that.

Partition tables also belong to the disk, not to the first partition, so
you should run cfdisk /dev/sdb.

Always try to do things in chronological order; it's less confusing that way.

You need to copy boot.img.gz to the disk /dev/sdb, not the
partition /dev/sdb1. I also don't see why mkdosfs would be needed as I
beleive boot.img.gz is a binary dump of a whole FAT file system.

See http://www.debian-administration.org/articles/446
I've just done this less than an hour ago, and have successfully
reinstalled Debian Testing on my netbook.

Note, the kernel in the boot.img.gz file has to be the same version as
in the iso file, otherwise you will get an error near the beginning of
the install about not being able to load kernel modules.

lol ! That was the key !

It did not work for me as normal user.

The next time I mounted the usb key, it properly showed up under
/media/Debian Inst. But again cfdisk believe the partion is corrupted:

FATAL ERROR: Bad primary partition 0: Partition begins after end-of-disk

Press any key to exit cfdisk


This is just for reference so that other people are not surprised.
Even with this error message, I could use this USB Key to at boot time
on a PC.

Thank you very much for catching my mistake !
