BSOD booting, error 0xC0000225

Hi everyone,
just read the post instructions up there, but I'm afraid I can't use the dump application because my sistem is giving BSOD on booting.

I got a dual boot with GRUB2, Arch Linux + Windows 7 Pro x64.

Always used it with no problems, and now the Windows loader can't work.

I only managed to read the status value, 0xC0000225, and something like "boot manager generic failure", "a required device is inaccessible".

I tried using the repair function from my full retail dvd, but it didn't work as well. I think it's because it acted on the windows partition, while the windows boot is stored in another partition of about 100mb, wich was created automatically during the dvd installation.

So I guess the solution would be giving to the repair function the right drivers to let it "see" the boot partition, but how?

Or, can I solve in some other way?

My system specs:

Windows 7 Pro x64
Full Retail
The machine is a laptop, 1.5 years old
OS installed a few months ago

Thanks in advance.

We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

If you are overclocking STOP

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.

To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

Followed your instructions to enable minidump using safe mode with prompt line (safe mode with networking didn't let me do this), but it didn't display minidump directory after reboot. Instead there's MEMORY.DMP.

Using safe mode with networking, I ran the bsod application, you'll find the zip attached.

Can't save a system health report: when I enter "perfmon /report", it displays:

Code:

The system cannot find the path specified.

Another thing that might be helpful: in safe mode, this warning appears in explorer:

C:\Windows\system32\config\systemprofile\Desktop refers to a location tha is unavaible. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location.

And I don't overclock.


Thanks for your time.
