Boot failure after install

People please advise me. I was running, quite comfortably Win XP Pro SP2 (320Gb SATA raid 0 stripe 0 2x160Gb), when I decided to try Ubuntu 8.04. Tried to install it within Windows with wubi but Ubuntu would not load. Un-installed it. Next tried to install it from within Ubuntu (System>Admin>install). God only knows what happened (probably lost my sanity for a moment!) and the next thing I know nothing works. Ubuntu or Windows. Is this the end of life as I know it?

Now, while I believe in miracles, here at least I am not expecting one. But, please is there anyway or recovering Windows and saving my data in the first place (biting my nails!)? Or have I lost it all? Any chance of a roll back?

I managed to boot the live CD and here is what I have to report... sob.. sob...

Disk /dev/sda: 160.0 GB, 160000000000 bytes
255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x41ab2316

Device Boot Start End Blocks Id System
/dev/sda1 * 1 18696 150175588+ 83 Linux
/dev/sda2 18697 19452 6072570 5 Extended
/dev/sda5 18697 19452 6072538+ 82 Linux swap / Solaris

Disk /dev/sdb: 160.0 GB, 160000000000 bytes
255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000

Disk /dev/sdb doesn't contain a valid partition table

So guys what is the prognosis? Is it terminal?

I need to have Windows working and then Ubuntu as dual boot. What are my options? And is it possible with my SATA raid 0 config.

Thanks for your time and help.

Now seem to have wiped out your disc off windows and ubuntu. But i have a question, what happens when you boot the machine? Any errors like grub not found? It is always imperative to first install windows before linux and this is incase u do need to do a complete reinstall.

There is a chance you might have lost your data but just post the output of the boot process

Thank you for trying to help even if what you said I was afraid of and it hurt!

The error I get is the usual, GRUB loading........ Error 2

That is all what happens.

Question, will I have to set my raid up again or has that been destroyed too?

Thanks again

Your fdisk results don't show any windows partitions so it looks like trouble. Did you have windows on sda1 (first partition)? It now shows as a Linux partition? Are you able to see any directories/files? Did you try mounting sda1 from the Live CD.

If things don't work out, I would suggest you google for SystemRescueCD and download it and see if you can save any data?

Yes it looks like Windows was on sda1. Since windows came pre-installed on raid 0 disk array (2x160GB). No files or directories can be seen.

Think Ubuntu very much wiped out the utility files and saved window files that come pre-installed by the manufacturer for just such a scenario. That means that I will probably have to re-do the whole thing.

Question - will I have to reconstruct my raid drives? Any help in that regard?

Thanks for the help.
