OS: Win7 Pro SP1 x86
Laptop: Dell Latitude E6410
Unable to boot into Windows and Safe Mode - both return the same blue screen. Most online resources explain that the bootcat.cache
(in %windir%\system32\CodeIntegrity\
) may be corrupt or the size of the file has unexpectedly changed.
Using a bootable Win7 USB drive and entering System Recovery Options, I can browse to this directory and see that there is no bootcat.cache
file (even when looking at hidden system files). After all the attempts mentioned below were made, the machine does not create a new bootcat.cache
file and, subsequently, will not boot into the OS.
I decided to create a valid copy of this file by recreating the OS using the same laptop. To do this, I removed the SSD from the laptop, inserted a new SSD, installed the same OS, booted into Windows (successfully), and copied the bootcat.cache
file to a USB drive. I put the original SSD back into the laptop, put the new bootcat.cache
file into the CodeIntegrity
dir, and received the same BSOD.
This SU answer explains the {F750E6C3-38EE-11D1-85E5-00C04FC295EE}
folder's relationship with the bootcat.cache
file. I have completely replaced this folder with a copy from new SSD with no results.
This article instructs to replace the ntdll.dll
found in %windir%\system32
, which I have also copied from the new SSD with no results.
Other attempts made without results include,
sfc /scannow /offbootdir=E:\ /offwindir=E:\windows
(correct drive letter)- delete McAfee from

Root - Have you already run a Startup Repair and just let it run to see if it finds any issues to resolve on it's own? I also didn't see that you had run the

When you say you're able to boot using the Windows 7 USB drive, are you able to browse the HDD that is mounted too? If you could get a .dmp file that can be run through WinDBG, that would be a good start. – DrZoo – 2017-01-24T20:22:47.927
I also noticed you said this I decided to create a valid copy of this file by recreating the OS using the same laptop. To do this, I removed the SSD from the laptop, inserted a new SSD, installed the same OS, booted into Windows (successfully). So you clearly overcame the problem. Why did you not continue using the new SSD? There seems to be something faulty with the other one. – DrZoo – 2017-01-24T20:25:33.733
@DrZoo I was able to browse to the SSD that was having difficulty. Minidump logging was not enabled in the OS. I can't agree that replacing the SSD allowed me to overcome the problem. The goal was to fix what was broken, not replace it. – root – 2017-01-24T20:29:28.573
