Hi Last week I turned on Acronis Recovery Zone (boots from F11) because I was having trouble booting from CD. I am now able to boot from CD, and want to turn off the Acronis Recovery Zone (when I activated it, I did not realise the implications for my Master Boot Record). When I turn it off, will my MBR roll-back automatically to the previous one? It is an Acer laptop and I want to go back to the factory-installed MBR where pressing F11 starts Acer recovery manager. Can anyone help with this question? Thanks, H.
