I'm having this problem every time I boot. Maybe someone can help me, either fixing the problem or recommending another distribution that can easily do software raids for dummies.

I have installed Ubuntu Studio 10.10 alternate, I have 6 HDDs, of which two form a raid 0 array for the system, another three form another raid 0 disk array for the swat and a data partition and the sixth is on it's own and serves as backup.

I have gone through this entire procedure three times and it happens in the same way every time.

At first all seems to go well. I install and get Ubuntu studio going with the desired raid setup. I then upgrade to a PAE kernel to fix the ram limitation as I have more than 3gb. It still works after this. Then Ubuntu wants to install "upgrades", and after all the upgrades (>250MB of upgrades) I get the "Error: no such disk" message when I boot and the grub rescue prompt. I does not matter which HDD I select in the bios, it won't work.

I have tried the supergrubfix2 cd, and that can't even detect an OS installed on the system. I'm using a live cd, ubuntu 10.04, and I can't mount the raid because the computer says "there aren't enough components to start the array". I've read there are many people around with similar problems but not quite the same as mine.

Here's the output text file from the boot_info_script if it may help.
