How to remedy boot loop with WDP enabled? RRS feed

  • General discussion

  • One of my sites has a PC (Dell Optiplex GX520, Windows XP Pro) that is currently going through a boot loop, trying to save changes to WDP. Once it "finishes" writing new changes to the boot record, the machine reboots itself and it then attempts to write changes to the boot record again. When I tried to boot off of my Windows XP Pro CD, it wouldn't let me attempt to recover an installation. I tried to run "fixboot" in recovery console, but when I tried to boot back into Windows, it would only start up with the "WDP is applying changes" screen and then the vicious circle starts around again. I'm trying to eliminate any and all possible options before having to do a full reinstall of the system. Any possible ideas?

    How about Safe Mode or Last Known Good Configuration mode?



    1. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple Operating Systems, you can press the F8 key when you see the boot menu.

    2. When the Windows Advanced Options menu appears, select Safe Mode, and then press Enter.


    Note 1: If we can't enter Safe Mode, I also recommend we try to enter Last Known Good Configuration mode.


    3. Log onto Windows by using the Administrator account or any user account with the Administrator privileges.


    NOTE: In Safe Mode, your system display and desktop will look and perform differently than in Normal Mode. This is only temporary. We can easily return to Normal Mode by restarting the computer.


    4. If we can enter Safe Mode, we can try to delete the WDP cache file from drive C, then restart the computer to check if this issue continues.


    If there is any update, feel free to post back.


    Best Regards,

  • Hi Shawn:


    Thank you for the reply. Unfortunately, starting in Last Known Good... and Safe Mode only gave me the same result. When selecting Last Known Good..., the XP screen started up with "WDP is committing changes" along the progress bar and subsequently rebooted and started the loop all over again. Safe Mode did the same thing.


    Unfortunately, I'm thinking more towards a hardware failure and the hard drive would have to be replaced. I'm hoping it shouldn't have to come to that, so if you've any other possible situations to try out, I'm all ears.

  • Hi,


    Are you sure you entered Safe Mode correctly?  You should not see the message about committing changes when you boot in Safe Mode.  Windows Disk Protection will go into a passive mode where it will not commit any changes or cache any disk writes when it's in passive mode.  If the system is still rebooting when you boot into safe mode, then it sounds like there's something else going on.
