LDrvPro64.sys is the driver file. Under normal circumstances, win7 system will verify the signature of each driver. Failure to do so will cause the system to fail to start, so this problem needs to be solved.

There are two solutions:

Method one,

1. You need to use F8 to start the advanced startup menu of win 7.

2. Select to disable driver signature enforcement.

Method 2: Enter the safe mode of the system, directly delete the LDrvPro64.sys file, and then enter the normal mode. The above is the operation method of prompting LDrvPro64.sys that the digital signature cannot be verified when Win7 fails to boot, which can ensure the user to start the computer normally.
