B/c Ubuntu does not, by default, install bootloader in the installed partition, it is not easy to chainload Ubuntu from OpenSolaris. Thus, you did a correct thing by installing OpenSolaris first. However, at the present time, Ubuntu's os-prober only probes Hurd, Linux, Windows, and xBSD, OpenSolaris insallation is not yet automatically probed (we hope this situation will be changed, considering that an increasing number of Ubuntu users are very interested in OpenSolaris). You have to do the chainloading manually. This is very easily done in Ubuntu 9.04 and previous versions; you simply need to edit the menu.lst file. In Ubuntu 9.10, which uses GRUB2, the procedure is quite different. You can't manually edit the /etc/default/grub.cfg file. However, it is still quite easy to dual boot Opensolaris 2009.06 and Ubuntu 9.10. The steps are briefly listed below: 1. Copy the attached "40-custom" file into /etc/grub.d , or by adding the following lines at thd end of your existing 40-custom file; menuentry "OpenSolaris" { set root=(hd0,1) chainloader +1 } 2. Run the update-grub command as root (this will generate a new grub.cfg file allowing you to boot into OpenSolaris; 3. Re-start your machine, selecting OpenSolaris as your boot option. -- This message posted from opensolaris.org
