[ Solved ] Repair STOP 0x0000006B PROCESS1_INITIALIZATION_FAILED Blue Screen Error While Booting Windows 7

by Rohit Khurana on September 3, 2010


Recently, on my windows laptop I faced this error of STOP 0x0000006B PROCESS1_INITIALIZATION_FAILED Blue Screen. I tried many times but windows does not even boot up in safe mode or any other mode after many tries.


After some Googling I came to know that error is actually a result of issue occurs because the Bootcat.cache file is corrupted or because the size of the Bootcat.cache file is changed since the last successful start.


In order to repair this issue, you will need to delete the Bootcat.cache file is located at %SystemRoot%\system32\codeintegrity – [ or C:/windows/system32/codeintegrity ]. Once you have deleted the file restart your computer normally.

A hotfix is also released by Microsoft to solve this issue, but as the computer does not boot up this fix cannot be installed. So, better boot your computer in another Operating System in dual boot if you have or boot up using Ubuntu live cd which you can download from here.

Do let us know if it does not fixes the issue, in your case.

Having this exact problem, the above fix does not work in my case.

I’ve deleted the bootcache file via command line in repair mode. Checked the disk, which has no errors, fixboot’ed and fixmbr’ed and generally applied all the repair utilities supplied by windows.

For the record, I’m an MCSE/MCSA and have no problems understanding the involved parts and procedures. This, however, does not make it work any better, as the only fix from MS does not do the job :)

Nope, still getting an error 6B.

I think this may also be related to a disk failure; i cannot seem to use system restore except for the most recent restore points and all other repair options do not seem to work.

i cannot force chkdsk to run, nor scf, and fixing the boot records has no effect either.

windows says it cannot fix the problem and it cant give me any useful information so i think the easiest option might be to load windows 7 back on to a new disk and rebuild my computer.

cant say im happy with this but i cant spare the time going round in circles.
