Computer won't restart: "Root cause found: Boot critical file D:\CI.dl

I was using the computer when all of a sudden it shut down. When I turn it back it on, it automatically tries to do a Startup Repair. After several minutes, I get the message: "Startup Repair cannot this repair this computer automatically." When I click on "View problem details," everything looks fine except for "Root cause found: Boot critical file D:\CI.dll is corrupt." This happens every time I try to retart the computer. I've tried System Restore and System Image Recovery to no avail.

Thanks in advance for your help.

Hi Carolyn,

I inserted the DVD and closed the Install Windows menu, but the computer restarts, and Startup Repair automatically opens. Now when I check the Diagnosis and repair details after Startup Repair is done, I get "Root cause found: Startup Repair has tried several times but still cannot determine the cause of the problem." So, I can't even get to the Start button/elevated command prompt/Run.

Not sure if this is important, but a few months ago due to a virus, I had to do a complete factory re-install.

Try replacing the ci.dll. If you ask nicely, somebody on a 64 bit system can upload their own copy of ci.dll. The file is located in C:\windows\system32. Sorry I'm right now on a 32 bit.

Copy the uploaded file to a bootable flash drive, then boot from the flash drive and copy the dll over to c:\windows\system32. Reboot normally.

Ok Carolyn Thank U for the help :-) and as for what i wrote earlier that was the result of me not typing in the right thing so i had to do it over twice smh. But everything went accordingly the last time all but part 18- Type copy *.* .. and press <ENTER> to copy the backup hive files to \Windows\System32\config.If you are prompted to overwrite existing files, press A to allow all file to be overwritten. when I tried this it said files cannot be copied onto it self do u think this is because i did it more than once? And once again thank U

due to a virus I had the same problem : infinite loop recovery and ci.dll corrupt...
i've solved the problem :
  • recopy the ci.dll to c:\windows\system32
  • and next repair the bootloader ( the virus delete infos in c:\boot...)
restart & enjoy :)

Dont waste time with windows rescue and reinstall until u try this

It's likely a TDSS rootkit that neither McAfee nor Norton will detect.
It will prevent the system from booting
It will get auto repair to go round and round
Auto repair will sometimes say its ci.dll and sometimes it will say it cant find anything wrong.
BEFORE you try to blast and reinstall:
Boot withtout driver sig verification, it will get you back your desktop,
and quickly use Kaspekerkys TDSS removal tool tdsskiller.exe before the rootkit does further damage by downloading other stuff.
Read up "How to remove malware belonging to the family Rootkit.Win32.TDSS"
Good luck

jlwu I tried this. I managed to get back on my desktop, but when I went to use the internet to download the tdss removal my computer blue screened. It was quite late last night and was my final attempt so sorry I have been vague, I'm not sure if this was down to using the internet or whether it was going to happen anyway.

I'm going to put the tdsskiller.exe on to a disc at work then hopefully load it before anything goes wrong.
Would be great to know how you loaded the tdsskiller.exe
