Vista - Missing BOOT MGR + BSOD/nvstor.sys

(I am posting here because i came across information via google that indicated the root cause to this problem was a windows update).

I have ASUS P5N-E SLI which has nVidia nForce 650i SLI, with Vista Ultimate 64 - all latest service packs installed. I purchased this system pre configured from a 3rd party vendor.
Recently, the system spewed forth "Missing BOOT MGR" message while attempting to power up the system. A bit of research lead me to attempt to boot from my Vista Ultimat 64 SP1 DVD. In the middle of starting up, my system spews forth a blue screen of death message that ends with:
nvstor.sys - address ffffa6000012f923e base at fffffa60012f3000, datestamp 46671a38
I have a lot of time invested on my current system configuration and would like to overcome this problem with the minimum changes.
Any suggestions?

Hi,

nvstor.sys is the nvraid storage driver(as far as i know). Yes u are right windows update is the cause of this problem.
Download the nvdia raid driver from this manufacturers site. update raid driver.

Let me know the result.

I got the files you suggested (attached is a list of files). But without the ability to boot and run Vista how am i to install these drivers?

The files list is attached.

Hi,

If this is my case, I'll install os in Recovery partition and move my data from c drive to another drive then i'll do clean installation on my c drive.

Am sorry to say that.

Hi Mark and Welcome to Vista Forums. Did you try this:
Bootmgr is missing

Thank you for that. The problem is that i get a BSOD when i boot from my Vista DVD - so i cannot reach the repair menu. I am in sort of a dead lock. The solution requires me to load the OS, but the loading of the OS is prevented by the BSOD because of nvstor.sys. I am guessing that some how i have to create a custom Vista boot disk that has the GOOD driver (or doesnt try to load the BAD driver). Since the consensus is that Microsoft caused the prblem, perhaps they will solve it with a nice custom boot DVD etc. I have a $59 call into them.... i will keep you all posted.

Hi,

If u are going to re install os then i'll tell u the procedure.

1.download the nlite deployment tool.

2. Follow the procedure and deploy ur os with the drivers which u already downloaded. Write the deployed image into a dvd and install os with that cd.

I assure u ill not get any error.

Dude it seems that you Geforce card is causing this problem. try removing the card and run the system on integrated video.

What Dinesh said.

And stay away from nLite - the machine has enough problems already.
