Damaged/unsigned AHCIX64S.SYS driver after unistalling AMD Catalyst
Hi there,
I will keep things short first, if anybody per chance knows this problem right from the start and how to solve it quickly. If u need more details on what I have tried so far or more details about my system. Just ask then i will provide all info I have. But I don't want that you read until you die...
Well it ain't a bluescreen but a Windows Boot Manager Error message during boot up of my Windows 7 64 bit Home Premium:
_________________________________________________________
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1 Insert cour Windows istallation disc ... blah
2 blabla
3 blabla -> "Repair your computer"
(Now the important part)
File: \ Windows \ system32 \ DRIVERS \ ahcix64s.sys
Status: 0xc0000428
Info: Windows can not verify the digital signature for this file.

This came directly after a reboot which I had to make after using the AMD Catalyst removal tool to remove my AMD Catalyst drivers 11.2 to install Version 13.4 because I couldnt uninstall via "Software" or reinstall the new drivers simply. So basically what happened is that the removal tool removed more than only my graphic card drivers. Safe mode wont work, its a more fundamental problem i suppose.
If I chose to "Disable Driver Signature Enforcement" via F8 Boot menu then there indeed is a Blue Screen
with Error code 0x0000007B (INACCESSIBLE BOOT DEVICE) which again points to the fact that the HD/RAID/AHCI drivers have problems initialising because they have been removed/manipulated by the Catalyst Removal tool.
I tried the Windows Recovery Automatic Repair tool but it wouldn't find my Windows installation.
I have a RAID0 on my system HD for which I always need to preload (F6) the RAID drivers before I install W7 on my computer, one time only of course. So in the Windows Recovery mode there is an option to "Load drivers" if the HD with the system is not found. I did download the drivers again from MSI and burnt them on CD (I didnt find my old one). I loaded the drivers and then he acutally FOUND my partitions and i could access the filesystem at the W7 Recovery Environment (Command Prompt i.e., or via "Open File" dialogue when trying to load more drivers). I retried the automatic repair procedure but it again failed with a "Bad driver" error in the detailed error description.
A possibilty would be of course to install W7 again with preloading the drivers and have my old Windows moved to a folder "windows.old". I started the setup routine and preloaded the driver, he found my partitions and even found the Windows installation. But I dont want to do this because it means I lose all my settings and profile information which is in my case very much work to resetup.
Do you know of any simple possibility to repair the AHCI driver without being able to login.
Or how to install it if I have the .inf file and the sys file and all the media needed. Can I inject this somehow? Do I need to offline edit the registry for this? Is there a possibility including a Linux Boot Disc?
I mean there has to be a simple trick to repair this because it even has access to the HD because I have the possibiliy to go to the F8 menu and chose "Safe mode" for example. Then during the "Loaded driver: xxx.sys" listing it will move through many drivers and show them as loaded. Then hangs and gives the initially stated error message. It's of course the same error I get when i try to start windows normally.
Only then I can even see the W7 logo screen (Starting windows) until the error appears.
Please help me I am so desperate.
Ty,
