Now this has me VERY confused.
See, there was once upon a time where I could fire up unetbootin or yumi, install a debian iso to an usb drive and be done with it. Now it fails installation on both of them (with yumi, installer doesn't recognizes the simulated cd-rom drive, with unetbootin it recognises it but fails to read some files after a while).
(Have In mind that I'm talking about a netbook here, so no real CD drive)
Now if you search for "debian usb install" I get some links that either assume a lot of things, or I'm too stupid to understand what is really going on, or were written by authors who where living in another universe that isn't mine. Something about just plain copying the debian iso to the usb drive and automagically works! (it doesn't actually) or some other needed file (boot.img) that also needs to be copied for it to automagically work! (it doesn't either).
So now I'm just out of ideas. I downloaded the xfce image from here: http://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/ Or that's what I think. There is a 10Mb difference between my iso and that iso, trying to download again, but that might be related with the fact that there is 800 branches in debian's directory tree so who knows if I ended up in the weekly builds or not...
