id summary reporter owner description type status component version resolution keywords cc guest host 10489 Guest freezes on boot Russw Host and Guest are Win XP SP3. The guest will start in Safe mode or with Guest additions NOT installed. If I install guest additions (in Safe mode), Guest will freeze on boot up and give me the red and black bars across the top of the screen. If I restart Guest about 10 times, it eventually will start, but I have to do this every time I want to run the guest. Guest was created in an earlier version of VB 4 and this has been happening in every version since then. Log is attached, I was told the problem is the guest is resetting itself over and over and I should post a ticket. defect closed other VirtualBox 4.1.14 fixed Windows Windows
