Windows 7: Computer won't restart: "Root cause found: Boot critical file D:\CI.dl

19 Apr 2011   #1

Windows 7 Home Premium 64bit
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.

1. Insert the Windows installation DVD into the DVD-ROM; Click Exit if the auto-menu pops up.
2. Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
3. At the command prompt, type the following command, and then press ENTER:
sfc /scannow

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
