System has two hard disks: 160GB SSD, which is the boot disk and 500GB RAID1 HDD.

I have Windows 7 Ultimate 64-bit installed as the main OS on the SSD. I don't want to touch or modify this drive.

The 500GB RAID1 drive had one partition: 1 primary NTFS partition for storage of stuff I want to access from Windows, and then about 200GB of unallocated space.

I ran the 11.10 installer, selected the "just install the stuff" option (the first one, I forget what it's called), and it installed it in the unallocated space, creating two primary partitions: one ~200GB ext4 partition for Ubuntu itself and another 12GB primary partition for the swap file (same size as RAM I have).

Problem is that Grub didn't install to the MBR on the boot disk (the SSD) so I have no way of starting Ubuntu that doesn't involve BIOS shenanigans. I am kind of apprehensive about manually installing Grub into the MBR of the boot disk myself so any guidance regarding if that's even what I need to do would be great.

FYI, I tried re-installing specifying everything manually, including setting the ~200GB ext4 partition to be the / mount point and telling the installer to install the bootloader on /dev/sda1 (I think, perhaps is was /dev/sda, I forget, exactly), and that didn't work, either.
