With the strict forum posting rules, I'm not sure what section this should be in but I woulld like to know if anyone has been able to back up their BT4 to an ISO and then make it into a bootable usb. In the past I simply used remastersys and unetbootin to do this, but BT4 doesnt seem to want me to do this. Is there something that Im no getting here or can I do it in a similar way to the original hd install method? Any help is appriciated so that I can backup my working version to allow me to safely test some changes (mainly updates). Thanks.....
