I just upgraded to Windows 7 Home premium from Vista home premium and when I try to perform a backup at about 20% done it fails and I loose my wireless mouse and keyboard function and have to reboot. I get error message Ox80070002. I have done a cmddsk /f/r on C: . Didn't seem to help. I have a HP AMD quad with 8 gig of Ram and came with Vista home premium with free upgrade to windows 7 which I have done. Anybody know what may be causing the error message?

Hi,Try following steps:Find this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileListRight click on ProfileList, click Export, export it to Desktop as a backup.Then please check each sub-key, find the ProfileImagePath value, check if it points to a correct path. If not (or there is no such a value), delete the sub-key.Reboot and check the backup again.

Hi Sharon, Thank you very much for the help. I have already gone to the ProfileList and done a backup but I am a novice when checking the register. I think I know how to check the sub-keys that are in the ProfileList, but am not sure what the correct path would be. Is it possible to explain what the correct path would be? Thank you again for the help. RogerDodger

Correct path means if it point to a location which does exsit.

Hi Rodger,Can you please send the traces for the backup failure which are located at %windir%\Windows Backup\*.etl to Soudamini[dot]Sreepada[at]microsoft[dot]com?Thanks,S.Soudamini.This posting is provided "AS IS" without warranties and confers no rights.

Hello, When I go to windir there does not appear to be a \windows backup\ ?? Any suggestions would be appreciated. Thanks you for your time. Roger
