Hi, I seem to have the same problem as Will (when trying to reformat, the \SystemRoot\System32\Config\SECURITY errror appears)
After reading the page linked, i am as lost as before. As I am trying to reformat, I know that my hard drive is compatible with XP-Home. The second solution tells me to use my Windows XP CD-ROM to access the recovery console, however, my Compaq Presario 6000 didn't come with one....
There is a second hard drive in my PC, which calls itself "Presario_RP" It contains the Compaq Recovery Partition.....would it have anything to do with this? :undecided
