The following was displayed in 'Automatic Repair' on startup:
"The operating system couldn't be loaded because a critical system driver is missing or contains errors"
"amdkmafd.sys" "0xc000007b"
I had installed the new windows 10 anniversary update (1607) and after finally sorting out everything to my liking I decided to boot up Radeon Settings to see if there was an update for the driver from AMD.
I was greeted with a message saying that the AMD driver was either missing or wasn't working properly and that I should go to AMD to download and install the correct driver.
Obviously confused as to why it would be missing or had errors I continued to download AMD's auto driver detect tool and ran it.
In the 'checkbox' stage of AMD's auto detect tool I saw that under all the items was a message saying that no version of that item was installed which I found rather weird that the drivers don't exist and the culprit initially points to the windows update I just completed.
I continued with the install and it was at that point when I experienced the BSOD.
The computer didn't restart after the BSOD so after some waiting I restarted it manually.
It then booted into Automatic Repair and the obvious route after the computer won't start due to the missing or corrupted system driver would be to use a recovery disk or USB.
Sadly I have neither.
(I have restore points but obviously can't get to them)
(I can't use the BSOD dump analysing tool for obvious reasons)
Any response would be greatly appreciated.
Hi GhostCatcher,
Welcome to the 10blog
I would need you to get into the troubleshooting options. After 3 failures of boot attempts you should get there automatically.
In the troubleshooting options, please run Automatic Repair at least 3 times with a reboot between each.
You may also want to go to the advanced troubleshooting options, open command prompt and enter following commandRun this command also at least 3 times with a reboot between each.Code:chkdsk C: /r
After that, try to boot again and let me know if you can boot succesful
Thanks for the reply!I would need you to get into the troubleshooting options. After 3 failures of boot attempts you should get there automatically.
Every single time I boot it says:
'Preparing Automatic Repair'
Then goes into a screen titled: 'recovery' with the following options:
Press Enter to try again
Press F8 for Start-up Settings
Press ESC for UEFI Firmware Settings
(Top one is to retry startup)
(Second details settings useless to me - Safe Mode and such)
(Third is bios which is also useless at this moment in time)
These aren't titled 'troubleshooting options' and there is not way to 'run' automatic repair.
I'm sorry if I seem incompetent :P
Choose F8, disable driver signature enforcement and see if you can boot, else try to boot into safe mode with the startup settings.
From safe mode we can try a few things.
Can't boot with driver signature enforcement disabled and can't boot into Safe Mode
There is only 1 safe mode.
Could you create a recovery media Recovery Drive - Create in Windows 10 - Windows 10 blog with another system?
I could create a recovery media on a USB with another system.
Would I only be using the recovery media to get into 'advanced options' when in 'troubleshoot' or would I have to use the recovery media to reinstall windows and lose all my data?
You're going to use the recovery media to see if we can get a solution for your problem. Reinstalling Windows is a last resort.
Thanks, I will now create the recovery media and will get back to you when I'm done
I have created and loaded up the recovery USB onto my computer.
I then opened up Command Prompt in advanced options and ran:
chkdsk C: r/
After completion I restarted the computer and it booted up into windows
Since the BSOD was caused when installing AMD Drivers after bootup of Radeon Settings showed a message (and still does)
'No AMD Graphics driver is installed, or the AMD driver is not functioning properly'
Trying to do the exact same process as last time may cause the same BSOD so my best guess is to use DDU and then install the drivers.
What do you think?
