    When booting my PC, and just after seeing the Windows XP intro screen, I am greeted with a message that says something like this.

    'Stop:C0000221 bad image checksum

    The image comdlg32.dll is possibly corrupt. The header checksum does not match the computed checksum.'

    I visited the microsoft page relating to this issue and have also tried replacing my RAM module for another known-good unit. Unfortunately, the problem still remains.

    I would like to replace the corrupted, or missing file, but can't make sense of the information that Microsoft have provided. Is there any easy way to replace this corrupted file by extracting it from the Windows XP CD and having it automatically overwrite the corrupted file without endless instructions?

    Have a read of Method 1: (as shown on the page http://support.microsoft.com/kb/326687 and see if it makes sense to you.

    As far as I can understand, I should insert a Windows 98 startup disk, when I am actually running XP?

    All of this aside, how do I reach a command prompt at which to type my instruction, when I cannot boot into Windows? Is it F5 at boot-up?

    Any advice gratefully received.

    I would use your XP CD to create a UBCD4win boot disk and see if you can boot with it >>


    I've attached a zipped copy of the file from my XP system -- you can put it on a thumb drive and copy it to the system32 directory once you have the boot disk loaded.

    This boot disk also has a "registry tools" section with a restore feature that might allow you to do a registry restore -- but this won't affect actual file corruption as far as I can tell.

    I'm not sure if you can choose the date or not.

    If not, be cautioned that this may restore the original registry files and you will need to reinstall subsequently installed programs if that is the case.

    Running chkdsk might also be advisable.

    You also have the option of doing a Windows reinstall -- just be advised if you do that you will have to reinstall all updates.

    And read this carefully:
