Vista blue screens while booting / attempting to repair

[Un Gato]

I'm trying to repair Vista so that I can boot without having to reformat. I can run Ubuntu off of a CD so it's more than likely just a problem with Vista. I have RAID 0, so recovering the data is almost certainly impossible. The details are as follows:

I have a Dell XPS 1730 laptop that has had some problems with unexpected shutdown, likely due to heat. I've had the heat sink and fan replaced, but the day before that occurred the laptop started blue screening every time I try to boot it up. This is the sequence when I try to turn it on normally.

The startup repair option here does not work, it simply refreshes that screen. I do have the original Vista disc (32 bit ultimate) and am able to run startup repair through that, but after several runs there's no indication it will be any help.

I tried a system restore as well, with no luck.

I'm trying to follow the instructions from here, but I'm not sure what letter to use in step three: "Replace x: in the commands below with the letter to your CD drive as detected by the Windows Recovery environment ." I'm not sure how to tell which letter refers to the cd drive, and e, the letter that I think used to be the drive, isn't working. This is as far as I've gotten: http://img23.imageshack.us/img23/7840/img0095hoj.jpg

As you can tell, that's not very far. I'm also a little uncertain about when to include spaces, as the vista repair page from this site seems to add unnecessary spaces prior to every forward slash, which I've excluded in my attempts.

When I run the chkdsk command this is what results: http://img193.imageshack.us/img193/9853/img0070muv.jpg

Sorry about the pictures being sized badly, but any help I could get on this would be excellent. If there's any way to not lose my data at this point it would be great.

According to the instructions, first you're supposed to type bootrec.exe /fixmbr (with nothing preceeding it), press the Enter key. I can't see in your image that you typed that command first.

The next line should be E:\boot\bootsect.exe /nt60 all /force, press the Enter key.

It looks like the problem has been you're typing the "x" that appears in the instructions when it should be replaced by E. If E doesn't work, try F and so on down the alphabet.

If that works, complete the rest of the steps in the instructions.

Good luck!

I'm not sure why you don't see it, it's right there. I ran bootrec.exe /fixmbr first and it completed successfully, the next line that I'm supposed to type didn't work. The X:\Sources> was there automatically.

My apologies. It is there. I shouldn't be trying to help when I really should be sleeping!

Based on what I can find online, it seems to be pointing toward hardware trouble.

Someone else may know exactly what that problem is, though.

Wouldn't being able to run Ubuntu suggest that it isn't a hardware issue?

I replaced the bootloader as described in step four here, I was messing up the spacing as I thought. The only change is that I now can try to open it in safe mode, but it blue screens all the same.
