And I do this without a separate /boot partition. 1. Go into the last operating system you installed, Studio64 if I understood you correctly. 2. Make a directory for each operating system you wish to boot into. such as: /UbuntuStudio /OpenSuse in the directory structure of your Studio64 system. 3. Edit the File System Table file, called fstab. You should find it as /etc/fstab. Specify the partions for UbuntuStudio and OpenSuse and have them mounted to /UbuntuStudio and /OpenSuse. 4. Reboot your Studio64 system so that the changes to /etc/fstab will be implemented. 5. You should now be able to change to the /UbuntuStudio directory under Studio64 and look at the /grub directory for UbuntuStudio. This will tell you which files you will need to reference in the Studio64 grub menu.lst file or grub.conf file. Do the same thing for the /OpenSuse directory. 6. Edit the Studio64 /grub directory menu.lst file or grub.conf or whatever it's called. Here's what I used to do when I was running Fedora and OpenSuse. Add the appropriate lines for the kernels you wish to boot. It's very important to comment out any "hiddenmenu" grub command. I've done that with #hiddenmenu below. The "timeout" grub command allows you the specified number of seconds you have in which to choose a Linux system to load. If you make no choice, then the "default" system is loaded. # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,0) # kernel /boot/vmlinuz-version ro root=/dev/sda1 # initrd /boot/initrd-version.img #boot=/dev/sda default=0 timeout=10 splashimage=(hd0,0)/boot/grub/splash.xpm.gz #hiddenmenu title Fedora Core (2.6.18-1.2798.fc6) root (hd0,0) kernel /boot/vmlinuz-2.6.18-1.2798.fc6 ro root=/dev/sda1 rhgb quiet initrd /boot/initrd-2.6.18-1.2798.fc6.img title openSUSE 10.2 (2.6.18.8-0.5-default) root (hd0,4) kernel /boot/vmlinuz-2.6.18.8-0.5-default root=/dev/sda5 initrd /boot/initrd-2.6.18.8-0.5-default Then to make life easier for yourself, boot into UbuntuStudio system and make directories for /OpenSuse and /Studio64. Update the /etc/fstab file for UbuntuStudio so that when you reboot into UbuntuStudio you can see all the files in the OpenSuse system and the Studio64 system. Do the same procedure for the OpenSuse system. Now, no matter what operating system you are in (as root), you can see all the files in the other systems. I think it's a very good idea to have the /Data directory in all the systems as well. This was the way I was able to share linux data with a Windows95 partition I also had set up. Just like with the other linux systems, Grub could boot into the Windows system. You just had to install Windows first, then install the linux systems. A final suggestion: I don't know why you would need a 20GB of Swap partition. I've got 1GB of memory and a 30GB hard drive. I am running without a Swap partition at all. I've rarely seen more than 500MB of my 1GB of memory being used at any one time. If you like, make your Swap partition 2 times your memory size, but no more. A thought.
