Hi,

today I couldn't boot my vista beta anymore.
I get the message:

File: \Windows\System32\Drivers\PxHlpa64.sys

Info: The image hash cannot be found in the system catalogs. ...

Yesterday I installed DivX, which doesn't seem to be compatible with vista.
Probably that caused the problem. I tried to repair the boot files using
the Vista DVD, but it doesn't work.

Can anybody help me?

Thanks.

Nico

Hi nri, welcome to BC.
You have a driver sig isssue, see the quote from MS below on the fix:

Quote

Setting the boot configuration. A boot configuration setting is available in the Windows Vista Beta2 release that disables the enforcement of kernel mode signatures to be persisted across boot sessions.
Windows Vista includes a command-line tool, BCDedit, which can be used to set the option in Windows Vista Beta2 to disable signature checks. To use BCDedit, the user must be a member of the Administrators group on the system and run the command from an elevated command prompt. An elevated command prompt can be launched by creating a desktop shortcut to cmd.exe, and then using right-click and Run as administrator.
The following shows an example of running BDCedit at the command prompt:

// Disable enforcement no signing checks
Bcdedit.exe set nointegritychecks ON

// Enable enforcement signing checks apply
Bcdedit.exe set nointegritychecks OFF

// Disabling integrity check on an alternate OS
// specified by a GUID for the system ID
Bcdedit.exe set {4518fd64-05f1-11da-b13e-00306e386aee} nointegritychecks ON

These Directions will get you into Windows without having to run the Vista CD recovery Disk.

How to Disable Signature Enforcement:
Using the F8 option. An F8 Advanced Boot Option introduced with Windows Vista Disable Driver Signature Enforcement is available to disable the kernel-signing enforcement only for the current boot session. This setting does not persist across boot sessions

Unfortunately, after I removed all the DivX components I get a different error when booting vista. This time it is not sufficient to switch off driver signature enforcement to fix it. The new error message says a critical system driver is missing or damaged (again PxHlpa64.sys, status: 0xc000000f).

Any help?? ;-)
