I use fsctl to get driver file sectors on disk, then write new driver file directly to the sectors via \.\physicaldriveX (my drivers all have same file size)… But when i restart system, i get windows boot error:
File: \WIndows\system32\drivers\xxxx.sys
Status: 0xc0000221
Info:Windows failed to load because a critical system driver is missing, or corrupt.
When i mount the disk on another system, i can see that my driver file has been updated. and I am sure that both drivers works well.
Good. Windows is correctly preventing a compromised system from starting.
