Oops - just fully read your post. I don't know why GRUB didn't get installed. How much space did you give OpenSolaris? The recommended minimum is 10GB. If you gave it at least this space, then it would help to know the layout of partitions and slices on your disks. (Slices are "sub-partitions" i.e. partitions within partitions, which some Solaris tools refer to as partitions).
Boot the OpenSolaris CD and run the "format" command as follows. (Don't worry - it won't immediately format your drive). 1. Get a root shell: pfexec bash 2. Run format: format -e Format should show you what disks Solaris has detected. It should also show you te device name it has assigned to each. This will be something like c4t0d0 . This naming scheme is explained here: http://sites.google.com/site/solarium/tips/disk-devices 3. Use the "fdisk" option in format to show the partition table on each disk. Make a note of the partition tables. 4. View the slices on each disk using the "partition" option in format. Once you are in partition, type "print" to print a list of slices. Make a note of the slices. Can you then post the partition tables and lists of slices here? Thanks Andrew. -- This message posted from opensolaris.org
