Ubuntu :: Kubuntu And Win 7 Run Without A Bootloader?

Kubuntu and win 7 have their own separate hard drives. The problem showed up when I installed the new Kubuntu 11.04 (disconnected win7 hard drive in hope that it wouldn't affect the win boot loader) . As of now, it's just an annoyance since I can just hit f12 quickly during startup and decide which one I want to boot. I tried doing what other tutorial suggest, but I am a little nervous about their instruction in reference to what number I should jot down since situation may be a little different.

Basically, I want Grub or whatever good working boot-loader to be installed (I heard a rumor that a click-able one was in the making) on my Kubuntu hard drive, and avoid affecting my win 7 hard drive (they research now with the updates to make sure you got their boot-loader running *sigh).

Here is some data I collected from partition editor, hopefully this will assist somebody in understanding my problem better:

ATA ST (where linux is installed)
/dev/sda1; type: ext4; size: 461.76 GiB; Used: 20.77 GiB
/dev/sda2 type: extended; size: 4.00 GIB; Used: 4.00 GiB
/dev/s...; type: linuxswap; size: 4.00GiB; Used: ---;
ATA WDC (Win 7 is installed)
/dev/sdb1; type: ntfs; size: 596.17 GiB; Used: 116.61 GiB
