Can someone please help with a multiboot problem.
I am trying to multiboot Windows XP, Mandriva 8, openSUSE 10.3, Ubuntu 7.10 and Fedora 7 with XOSL as my boot manager. I have a 40 gig hard drive on primary IDE as master and a DVD writer on secondary IDE as master with a 500 gig SATA hard drive which the BIOS calls 3rd IDE. I am trying to use the SATA drive as my main drive with Windows on a 20 gig primary partition and each Linux distro on its own 10 gig logical partition with a common home logical partition. I can get all systems to work except for Ubuntu, which will not install the Grub boot loader to its own root partition. Ubuntu insists on putting its boot loader in (hd0) whatever that is and therefore fails to boot from XOSL which is also on its own small partition.
I have even tried disconnecting the Primary IDE before installing Ubuntu, that didn't work either. How to I force Ubuntu to install Grub to its own root partition. Any help would be greatly appreciated. Thanks.

I only use the alternate CD for Ubuntu, but it certainly has the option to install to either the MBR (hd0 as you stated), or to the root partition.

You should be able to fix that within installer,maybe you just don't use partition you should for grub installation,but you can use Ubuntu to boot all the others if you know what I mean.
