After installing the new driver for virtual box guest addition following instruction given in the user manual, then reboot my vista based PC. However, after rebooting, only a blank page was displayed. My intention to use the virtual box mainly to test out various beta software without leaving any registry keys behind after uninstall them. I need to use the exact replica of my existing pc setting ( as well as web browser etc )for this purpose. I have read again and again all the info available but found that installing the virtual guest addition is the only way ( kindly advice if I was wrong because i really have difficulty to understand the manual). Taking the risk, I installed it. Since i was unable to logged into window to see if it works, i just have to perform system restore so that my pc function as usual. I was unable to test if i can run the exact replica of the host operating system ( my pc) in the virtual box. I have tested various linux system and it worked out fine ( because i do not need to install any additonal new driver ). I still searching for info on how to run host operating system within the virtual box...... Your advice on this matter would be greatly appreciated. thank you kavi (geneq18@yahoo.com)''''''" defect closed other VirtualBox 1.5.2 invalid other other
