I have two hard disks, one SATA, another IDE. On the SATA I have Windows 7, on the IDE I have Ubuntu 9.10. The SATA drive is set to boot by default. After installing Ubuntu, GRUB automatically installed itself on the first hard drive/MBR. This means GRUB booted whenever the SATA drive booted, I didn't want this. I wanted the Windows boot loader to boot Windows by default and GRUB to load when the IDE drive is selected. So I reinstalled the Windows 7 boot loader which wiped GRUB clean off the MBR so now Ubuntu doesn't boot. I want to reinstall Ubuntu but how exactly do I set GRUB to install onto a partition of the IDE and not the first hard drive/MBR?
