Grub Bootloader authentication
I am a newbie. I am trying to get MBR shadow working. I have 2 physical memories in my system. i.e. I have the MBR/grub with password enabled on flash 1(read only) and the other flash memory will have it's own MBR and corresponding OS(say windows).
I want to boot grub, enter password and then have it jump to the MBR on the second flash. However, if the OS on the second flash reboots(soft reset with no power loss), I want it to go through grub again(residing on flash 1). How do I achieve this?
