I currently have Vista Ultimate 32bit installed on my system in a RAID 0 setup. I have set aside 30GBs to install Ubuntu and to mess around with Linux again. The problem is that when I go to install Ubuntu, the setup sees it as two different drives. How do I get the setup to see the RAID partitons and how do I go about setting it up?

My system specs are as followed:

Intel Core 2 Duo e6300 @ 2.8Hz (for some reason, it won't go faster)
Cooler Master Gemini II HSF w/ 2x 120mm Scythe Minebea NMB fans.
Intel D975XBX2 "Bad Axe 2" Mainboard.
2x 1GB Buffalo FireStix DDR2 PC-8000 ram.
2x Samsung SpinPoint P Series SP2504C 250GB HDs in RAID 0.
2x Samsung SH-S182D/BEBE 18x DVD+/-R/RW DL DVD burners.

Partition setup:
C:/ 435.76GB - Windows Vista Ultimate 32bit
30GB - *unpartitoned, space for Ubuntu*

Update: openSUSE 10.2 does see my RAID array without any issues and installs on it no problem; however, it can't install GRUB/LILO on the MBR. Anyone have a clue on how to do it?

Its unlikely that you'll be able to install linux on the same RAID as windows. This is because most raid cards unload alot of the work on the processor and so the raid is done in the OS not by the hardware. This means that getting two OS's to use the same raid is next to impossible. Also Ubuntu doesn't install well to raid devices (it can be done, but you really need to know what you're doing).

Your could install Ubuntu to an unused partition on one of the drives. This assumes you have the drives split into multiple partitions and are not mirroring the whole drives (which is then partitioned in windows).

If you can't do that just get an old 30GB drive and stick it in there. This is the simplest and safest course of action.

Ya something like that.

The raid supported by your motherboard is typically called 'bios assisted raid' or 'fakeraid', among other things.

The deal is that it's like a Winmodem vs a real modem.. the hardware has been replaced by special software drivers. So basicly, with a bit of help from your motherboard your using software raid in Vista.

Now to do the same thing in Linux, were you use 'fakeraid' you have to use special drivers called dmraid. If your hardware is supported by dmraid then you can install and run Linux on the same fakeraid array as you do with Windows.

Typically if windows compatability is not important you'd just run using native Linux software raid, which is generally considered superior to the software raid support that is provided by the motherboard makers.

Ubuntu does not support dmraid with it's installer. (it does support Linux 'MD' software raid) It's possible with a bit of work to make the installer work with dmraid, but it's not easy for a new Linux user.

Thanks for the advice. I think now I might have to see if I can just install it over a USB drive. I wonder how responsive the system would be with a USB 2.0 HD for just general usage.

I had to muddle through this process just this week. The openSuse installer couldn't repartition the drives correctly. I gave up and broke the mirror, disabled RAID, and went on my merry way :)

Edit: RAID 1 for me, not 0
