Ubuntu ist wahrscheinlich zu sehr automatisiert was die Installation angeht. Man kann den grub auch woanders installieren als in den MBR.
Bei meinem Debian werde ich immer gefragt wohin der grub installiert werden soll.
Nur wenn grub andere Betriebsysteme starten soll, muß grub in den MBR installiert werden.
Du kannst den grub auch in die root Partition (/ Verzeichnis) von Linux installieren und unter Windows einen Bootmanager wie den von Acronis Disc Director 10 installieren.
Der grub wird dann von diesem Bootmanager gestartet. Du kannst aber auch den Bootmanager von Windows nutzen.
Ich weiß nicht ob Ubuntu dir die Auswahl läßt wohin der grub installiert werden soll.
Du kannst aber auch nachträglich den grub in die root Partition von Linux installieren:

3.2 Installing GRUB natively
Caution: Installing GRUB's stage1 in this manner will erase the normal boot-sector used by an OS.
GRUB can currently boot GNU Mach, Linux, FreeBSD, NetBSD, and OpenBSD directly, so using it on a boot sector (the first sector of a partition) should be okay. But generally, it would be a good idea to back up the first sector of the partition on which you are installing GRUB's stage1. This isn't as important if you are installing GRUB on the first sector of a hard disk, since it's easy to reinitialize it (e.g. by running `FDISK /MBR' from DOS).
If you decide to install GRUB in the native environment, which is definitely desirable, you'll need to create a GRUB boot disk, and reboot your computer with it. Otherwise, see Installing GRUB using grub-install.
Once started, GRUB will show the command-line interface (see Command-line interface). First, set the GRUB's root device4 to the partition containing the boot directory, like this:
grub> root (hd0,0)
If you are not sure which partition actually holds this directory, use the command find (see find), like this:
grub> find /boot/grub/stage1
This will search for the file name /boot/grub/stage1 and show the devices which contain the file.
Once you've set the root device correctly, run the command setup (see setup):
grub> setup (hd0)
This command will install the GRUB boot loader on the Master Boot Record (MBR) of the first drive. If you want to put GRUB into the boot sector of a partition instead of putting it in the MBR, specify the partition into which you want to install GRUB:
grub> setup (hd0,0)
If you install GRUB into a partition or a drive other than the first one, you must chain-load GRUB from another boot loader. Refer to the manual for the boot loader to know how to chain-load GRUB.
After using the setup command, you will boot into GRUB without the GRUB floppy. See the chapter Booting to find out how to boot your operating systems from GRUB.
"This command will install the GRUB boot loader on the Master Boot Record (MBR) of the first drive. If you want to put GRUB into the boot sector of a partition instead of putting it in the MBR, specify the partition into which you want to install GRUB:
grub> setup (hd0,0)
"
Du brauchst nur die Bezeichnung der root Partition von Linux anzugeben. In deiner menu.lst steht root (hd1,1) . Deshalb brauchst du nur setup (hd1,1) zum Schluß angeben.
