Vista Business boot loop after virus removal (using AVG)

Hi CleaverX,

I did manage to boot into Safe Mode (F5) before writing this forum thread. Furthermore using Safe Mode I performed a System Restore (to about a month ago), however the problem remains.

When AVG detected and removed the virus I suspect that it corrupted or otherwise affected (deleted or quarantined) an important file related to Windows booting correctly.

Since receiving your feedback I have used the following 'Advanced Boot Options' (F8) -

• Last Known Good Configuration (advanced)
• Disable Driver Signature Enforcement

After each of the options above I have rebooted, and in all cases the same 'load loop' behaviour (as shown in the original video link) has persisted.

Finally I have loaded the Windows Vista installation disk and selected 'Repair your computer'.

The 'System Recovery Options' dialog box does have my Vista install listed under the 'Operating System' column, and I am able to click on 'Next' and proceed to the list of available options. However when I choose the top option 'Startup Repair' there are no issues found (as shown below)!



I am now considering Command Prompt Options, such as 'Fixboot', however I would like some advice before doing so. Can you please offer further suggestions?

Kind Regards,

David

Hello blues_harp28,

Thank you for your advice. I have renamed the indicated files but am now seeing the error message below when attempting to boot into Windows -



If I click on OK the message dialog disappears for a short time, the display behaves similarly to the video that I first posted, and then the dialog above is presented again.

Do you have any other ideas about how to fix this?

Kind Regards,

Davo

Hi, Avg like most programs links into the system files and if something goes wrong with their files, it affects the whole operating system.
My next move would be to back up all needed data and files and try a repair install.

You should be able to save any needed files and data etc by using something similar to this.

Hi blues_harp28,

Before I follow your suggestions I thought it wise to post the results of 'bcdedit /enum' -



Is there anything from the above screen photo that might help me to avoid reinstalling Vista?

Thanks
