ok i am checking this
https://help.ubuntu.com/community/Installation/FromUSBStick
using the isotostick.sh method.

I run the laptop from the USB drive and the installer starts working 
fine, great!. But soon it doesnt find the cdrom so it cannot continue 
the installation process. It is basically trying to read the instalation 
files from the cdrom -which doesn exist in this case- so it fails.

At the bottom of the web page i am following it says that
when using the alternate CD installer one needs to setup the cddrive
the section is called "Mounting the USB stick as /cdrom". This are the 
commands to do it, one needs to open a new console with ALT+1 after 
choosing installation language

# mkdir /cdrom /dev/cdroms
# cd /dev/cdroms
# ln -s ../sda1 cdrom0
# mount -t vfat /dev/cdroms/cdrom0 /cdrom

I tried following those tips but still it does not find the cdrom. My 
usb drive shows up as sdb1, i checked read that from dmesg.

so i am stucked here at the moment. anyone has some tips? i am not very 
good at the debian install process, i am spiled by the Ubuntu livecd 
install system, so i am not sure how to go about this.

btw. i think that, once a solution is found, it would be good to have a 
howto about this somewhere in ubuntu studio website (maybe the wiki) as 
there are few laptop models with no cd drive. Mine is a Thinkpad X32, I 
bought it second hand on ebay and without the dock.

thanks!
