http://ubuntuforums.org – I want to install 12.04 on one hard disk and Windows 7 on another. Windows 7 is set already installed on one hard disk, but when I try to boot to it I get a "grub rescue" prompt and I don't know what to do with that. I installed 12.04 to the other drive and again I got the grub rescue prompt when I restarted the system to complete the installation. I want the boot loader screen to appear at each bootup and I want the option to boot to either operating system, with ubuntu being primary (default). On which drive, windows of ubuntu, should I place GRUB2 bootloader? How should this dec (Hardware)
