Cannot make network installer bootable from USB

I’m following the instructions here: SDB:Live USB stick - openSUSE
First I installed syslinux and then in console typed

jc_lara@linux-ybrm:~> isohybrid openSUSE-12.1-NET-x86_64.iso

No output, even using echo $? it gave a 0, so I guess there were no errors.
Then I plugged my USB memory and went on:

jc_lara@linux-ybrm:~> su
jc_lara@linux-ybrm:~> grep -Ff <(hwinfo --disk --short) <(hwinfo --usb --short)
disk:
/dev/sdb Kingston DT 101 II
jc_lara@linux-ybrm:~> umount /dev/sdb
umount: /dev/sdb is not mounted (according to mtab)
jc_lara@linux-ybrm:~> dd_rescue openSUSE-12.1-NET-x86_64.iso /dev/sdb
If ‘dd_rescue’ is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf dd_rescue
jc_lara@linux-ybrm:~>

dd_rescue command doesn’t exist! Heck, what am I doing wrong? How can I make a bootable USB with the network installer ISO? Can anyone help me, please? Thanks…

you can simply use dd instead


dd if=openSUSE-12.1-NET-x86_64.iso of=/dev/sdb bs=4k;sync

Did I mention that I’m trying all of this on openSUSE 11.3 x64?
And why does dd has a different syntax than dd_rescue? What is “bs=4k;sync” for?

I do not know the syntax of dd_rescue so I cannot tell you why it is
different.
From “man dd”:

bs=BYTES
read and write BYTES bytes at a time (also see ibs=,obs=)

you can also omit it, I add it mostly without any thinking because I
almost always add it.
sync is an extra command (it is separated from the dd command with a :wink:
it ensures that everything which is in the write cache is flushed before
it returns to make sure you do not unplug the usb too early.

“dd_rescue” is just a simple command that does part of what “dd” does, with some additional error checking. But it is not part of a standard install, so you need to use Yast software manager to install it before using.
