I'm having a problem installing Kali with a mini ISO burned to a CD. I can get all the way to the "Select and Install packages" step, but when progress reaches 90%, an error pops up stating that an error has occurred in this installation step. If I try to relaunch the "Select and Install Packages", it immediately pops the same error. In the syslog debug log (near the bottom), it says that there was an error with "umount: can't umount /target/run: Device or resource busy". Does anyone know whats wrong with my install?
