Is it a hardware or software RAID setup? – dobey Nov 8 '12 at 14:38
it is directly seen as raid on the BIOS of the system so i think this makes it a hardware RAID setup? – user1649238 Nov 8 '12 at 14:48

From the RAID page on Ubuntu Wiki:

Hardware Raid

Real hardware raid systems are very rare and are almost always provided by a card
such as a PCI card. Your hardware will need kernel level support in order to work
with Ubuntu. You can find out if is is supported without much work by booting a Live
CD. Your array should be visible as a scsi block device and if it has existing
partitions and file systems, mountable. 

So it seems like if Ubuntu is unable to see your BIOS RAID configuration, then perhaps the RAID controller chip is not supported by the Linux kernel in at least the version of Ubuntu you're using as a Live boot image.

ok, i can see the two raid disk on the disk utility of ubuntu but can't mount them. – user1649238 Nov 8 '12 at 15:31
Likely due to a driver, or hardware issue. RAID 0 is not a good setup to use, as if any of the disks within the array fail, you'll lose access to all the data, as it is interspersed across both. You might be able to recover if you use a Windows recovery image with the drivers for your hardware installed; assuming the disks haven't actually failed. But I think at this point, the question is also no longer appropriate for AskUbuntu, as it is about recovering a Windows installation. – dobey Nov 8 '12 at 15:38
right, we're installing windows and seeing if we can recover windows installation, if we can't we'll just have to format drive i think :/ – user1649238 Nov 8 '12 at 15:50

You almost certainly have a fake raid controller. You will need to install the dmraid package to recognize these. You can read more at
