i have the option to continue on from this error message then i get a small pop up box called  "dell backup and recovery manager" and it says "updating files" with a never ending looping green progress bar.  as far as i can tell the pc is doing nothing, no HD activity or net access.  ive left it doing this for some 2 hrs with no change.  when i ctrl alt del and get task manager up i can end the process, the pop up box dissapears and the recovery manager loads up for about 5 secs then dissappears.

 

ive tried to repair it in control panel but but it asks for SetupDBRM_ENG_64.msi file which i dont have and dont know where to download

 

ive also tried to download this which i presumed was the  recover manager but after i installed and ran it it came up with a fatal error, saying "This system does not have the Windows Recovery Environment installed"
