Grub not listing windows

[p3thead]

Hi I got three harddrives two 250gb and a 500gb and yesterday I installed windows on a raid 0 with my two 250gbs and today I installed Ubuntu on my 500gb drive but grub ain't showing the windows as a boot option, I've tried sudo update-grub2 but it just lists the regular :

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.0.0-16-generic
Found initrd image: /boot/initrd.img-3.0.0-16-generic
Found linux image: /boot/vmlinuz-3.0.0-12-generic
Found initrd image: /boot/initrd.img-3.0.0-12-generic
Found memtest86+ image: /boot/memtest86+.bin
done

How do I get my windows onto the list?

How was your Windows RAID setup? Hardware, software, built into the motherboard?

If it's a softraid then you may be out of luck with getting grub to recognise it.

It's built into the motherboard

GA-870A-UD3 if it matters.

If it's built into the motherboard then it's probably not hardware RAID, instead it's probably what's known as softraid, where the motherboard does some of the work and the Windows drivers do the rest. I really don't fancy your chances of getting grub (or linux in general) to recognise the array.

Saying that, I don't actually have any personal experience with such a setup so hopefully someone who does will prove me wrong.

I do not know RAID, but saved these links.

Also for installing on fakeraid (motherboard raid), this might help you:

Thanks for the links they were very helpful, however I finally solved the problem with the help from this link: http://www.linuxquestions.org/questi...ivated-785597/

Just had to run

sudo apt-get install dmraid
sudo dmraid -ay
sudo update-grub2

And then it added windows to the grub list.
