UNIX partition can't be recognized by Ubuntu

I'm trying to install Solaris 10 along with Ubuntu (dual-boot system)
The problem is, GParted partition manager (Ubuntu) didn't recognize the FAT file system used to install the Solaris. It said that the block size is unknown file system..

What's the correct file system to install Solaris so Linux (Ubuntu) can recognize?

FYI: I'm using Solaris 10 x86 and Ubuntu 7.04


Thank you...

Do you really need Ubuntu to recognize the alien disk? If you just don't use it for anything, you should be able to proceed. (Of course, if you want to be able to read and write to that disk, you have an issue.)

I'm trying to make a dual-boot system. I have problem with editing the /boot/grub/menu.lst on Ubuntu. When I reboot the system it doesn't recognize the Solaris file system. I don't know if it's connected...

Grub troubleshooting can be pretty thorny. If Solaris was able to boot off that partition before you installed Ubuntu then it should be possible to coerce Grub into reading it, but we need lots more information. fdisk -l output and the pertinent snippets out of your menu.lst could be a start. What have you tried so far?

I cannot perform the fdisk -l

# fdisk -l /dev/sda
Unable to open /dev/sda

When I looked my disk via GParted it said that my disk is /dev/sda
How come?
I'm trying to make tri-system boot to be honest. When I combined Ubuntu and WIndows there was no problem.. It worked well when I combined Solaris and Windows..

I've followed this step but nothing happened.. The Solaris still could be booted.
Should I use OpenSolaris instead of Solaris X86?

You need to be root to run fdisk, is that the problem?

From my OpenSolaris experiments, which admittedly haven't been too thorough
I recall that on the BigAdmin Website or some OpenSolaris site (was it called Solarium?) there exist Howtos that outline how to install a multi-boot scenario successfully.
I think one major issue was that you needed a special version of Grub
(maybe a patched one) that the OpenSolaris installer ISO ships
because grub must be able to address those BSD/SunOS kind of slices within the DOS partitions.
So that one can state things like
Code:
root (hd0,2,a)

which to my knowledge most grub versions shipped with the Linux distros can't understand.
The recommended procedure was to install Solaris last (after Windows, Linux) and install the grub that comes with Solaris.
Then of course, for any modifications in the grub's menu.lst you would have to boot into your Solaris first (which can be a bit nagging)
I am not sure if there are any Linux kernel drivers for SUN's UFS filesystem support.
But even if, mounting those rw under another OS always is considered suboptimal.
Just search docs.sun.com and the various Solaris forums/sites.
There you should find an abundance on multi-boot.
Maybe this will help for a start?
