Hi,
Having disabled a couple of (seemingly innocent) drivers/DLLs using the Auto-Start Manager in AU4 (expert mode), My win2000 laptop now BSODs halfway through the startup process with "Innaccessible Boot Device".
So, can I undo the ASM changes from the Comd prompt or recovery console? Are the Auto-Start Manager registry changes backed up in the usual place? If not, I wish they were!
I don't want to have to restore from NTbackup etc. if I can help it.
Many thanks,
Tom.
Restoring Startup Manager changes from the Comd Prompt
Hi
This is why we allow only experts to modify the drivers.
The drivers are in the below key. There will be subkeys with names similar to the driver name.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
Check for keys which have a value 'AutorunsDisabled' set to 1.
But you cant edit it from the command line to the best of our knowledge.
You might have to restore registry backups from system restore.

What about "Last Known Good Configuration" and safe mode ?

Hi,
Many thanks for the prompt reply.
Yep, hands up, it was definitely my own fault for tinkering
. I thought I'd played it safe, disabling only the keys to hardware/software that no longer existed. I've been using AU for many years and I just got too adventurous.
Sadly I tried "safe mode" and "last known good" to no avail. Do they employ backup registries? Does that discount any of the startup modifications? I seem to have trashed one of the early harddrive drivers mandatory to any bootup config.
Hopefully I can use the recovery console to reinstate last week's backup registry. If the crash had been a result of a "Clean System Registry" action I assume I could have just 'merged' the last AU backup file using reg.exe. It's a shame the Auto-Start Manager registry changes aren't backed up in this way to support a similar easy fix.
Any further thoughts greatly appreciated.
