Corrupted OS files preventing boot after failed driver update

I've been trying to get my computer back so that I can at least get some stuff on it I don't want lost for the past three days. I was updating an nvidia graphics driver and it froze. So I restarted my computer and things went down-hill from there.

Nothing I know to do (which is more than the average person) works. So most of (and perhaps all of) the quick fixes you all may suggest most likely have already been attempted at least once.

What I am experiencing now is a black screen with a gray bar on the top and bottom. The top is titled: Windows Boot Manager. This is written in the gray bar. The rest of the screen reads:

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your windows installation disc and restart you computer.
2. Choose your language setting and then click "Next."
3. Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacture for assistance.

Status: 0xc000000f

Info: The boot selection failed because a required device is inaccessible.



I am hoping someone can help me get make it so I can at least get some files off. System restore or anything like that is out of the picture because I was planning on getting an external hard drive for backing up, and haven't been able to yet. Ironically, payday is this Friday. :cry:

Anyway, I've even tried using ubuntu and also putting the HDD in another computer. Both ways it says that I can't get to it. When trying through the other computer, which has Windows xp, it says it's corrupt and cannot be used and what not.

How the heck can I repair the OS install (or whatever is corrupt) enough so I can get some stuff off before I do another clean install? Is it possible?! Please help!!

P.S.
My friend helped me try to do an error-checking on through the xp computer. Did nothing. Would it work on a Win7 computer?

Did you try the suggested startup repair options with the windows 7 dvd/repair disc?

It may take several runs and will at least attempt to repair the partition table.

If you tried that already , then use the commands instead of auto startup repair - usually does the job.

If you have the disc and want further advice, post back.

If you don't have a 7dvd/repair disc , get one from here - the same bit version as your installed o/s ( torrent, but it's usually quick ):

Boot it up go to command prompt , run checkdisk e.g. chkdsk C: /F , then

Type:

diskpart

(then press enter )

lis vol

(then press enter - make a note of the windows partition letter, and the 100mb partition , if you have one).

sel vol z

( replace z with the letter you got for the 100mb partition - if you haven't got one - use the letter of the windows partition- then press enter )

act

EXI

(to leave diskpart)

bcdboot y:\windows /s z:

(replace y: with letter of your Windows partition , and replace z with letter of your 100mb partition - if you don't have one - use the windows partition letter in both places -then press enter)

bootsect /nt60 all

(then press enter).

Restart pc

Question!

For the first part you have :C /F. I just want to clarify what you mean by that.

If you type chkdsk C: /F in the command prompt it will check the disk ( :) ) with the drive letter/partition C: and it will /F fix any errors it finds.

A little more info from you would help.

What messages did you get from running each of the commands?

All right, so I CAN'T do it again. I think we broke it further.

My last update was that the problem from the first post is replaced with the "BOOTMGR...." message. And trying the very first step you gave me now doesn't work.

Bootmgr missing usually means the wrong parrtition is active.

However, it may be due to corrupted file system in your case.

Best option - restore your most recent backup image.

If you haven't got a backup image - reinstall is what you are left with.
