Hey all,

Thanks for you feedback.

@Loomx interesting. For some reason it didn't work for me until I ran the scripts that makes it hybrid. Must have done something wrong. Maybe it failed for a totally different reason.

@Mike I believe CD iso images are read only by design, no matter whether the medium they're copied to could be written on. There is another slightly less intuitive way to create a installation usb drive. There is a usb image here:

https://mirrors.slackware.com/slackware/slackware-14.1/usb-and-pxe-installers/

which can be copied to usb using the usbimg2disk.sh script. But you will have to copy the contents of the installation DVD over to the stick yourself to get a full installation medium.
