My understanding is that the set of instructions I've been given by the MB Helpdesk are intended to copy a system.bak file from the repair folder on my corrupted laptop into the system 32\config folder, having renamed the earlier (and corrupt) version to system.bak This is an extract from the instructions I was given 12) Once you have correctly entered the administrator password, you will be shown something that looks like the following line: C:\WINDOWS>_ 13) You can now type out the following commands, one at a time, making sure to press enter after each one. Each command is on a separate line. Please make sure that you type them exactly as they are shown here, and pay special attention to the placement of the period after a blank space on the third line: cd system32\config ren system system.mbam copy ..\..\repair\system . exit 14) After typing 'exit' and pressing 'Enter', your computer should restart. Make sure to remove the CD. The bit I'm having a problem with is the copy ..\ statement above. I've established that a folder windows\repair does indeed exist on the laptop and within it is a file system.bak so, assuming my understanding of what we're trying to achieve here is correct, its just a case of getting the correct statement to copy the file from c:\windows\repair to c:\windows\system32\config Anyone help ?
