If you are getting constantly looping Startup Repair in ordinary boot and in SAFE mode and a report of a ci.dll problem, see this thread. The ci.dll file is not the trouble. It opens a kernel file and if that has a problem you will get the ci.dll fault report.
The problem is usually caused by downloading stuff from the net that contains a very nasty rootkit virus/trojan. It is often in a .rar file. This is not spotted by a lot of virus killers, It overwrites your boot and drive headers so there is no easy way to kill it.
My thread gives you more info on what to do and what not to waste your time on.

Just going to be honest here about how I got the infection, detected it, and removed it.


I am usually a very careful browser but I got sloppy and picked up the the boo/tdss.m trojan while browsing some of the more dangerous pornsites out there in search of legal but obscure content. While browsing my pc crashed and re-started in Startup Repair tool, kept looping and when I looked in details it was the ci.dll issue.

Found this thread and did not have a way to open up HD and remove it "remotely" by opening it as a slave drive on another PC.

I used the Avira Rescue Bootdisk to confirm I had the boo/tdss.m rootkit.

After searching around how to repair boot records I found out about Bootrec.exe (a built in windows executable)

After getting into the command prompt via a install disc(you can also access it after the Startup Repair tool "gives up" on trying to remove it "Advanced Tools"), I was able to run 'bootrec /fixmbr' which re-wrote the boot sector.

That fixed the ci.dll error, allowing me to boot into windows and also apparently completely removed the trojan as I am not getting anymore detections on any scan. I am glad this worked as I have lost my win 7 upgrade disc/key and would of been without a legitimate license if I had to re-install.

Install, update and run full scan with Malwarebytes
to be sure you've gotten rid of infection since bootrec commands cannot remove it.

Next uninstall your failed AV, install Microsoft Security Essentials,
run a full scan.
