stick with whatever was last bootable! flopping to-fro is a pain.
first chore is to get a CD that will boot OR try booting into SAFE MODE;
- from a powered off condition, start the system
- immediately start pressing/release/pressing your F8 key until you get a prompt
- if you get the opportunity, choose SAFE MODE
if this doesn't work, you'll need the bootable CD.
your object is to get the registery recovered. there are copies located at
c:\System Volume Information\_restore{....}\RPnnn\Snapshot\
and the files found there are
• _REGISTRY_USER_.DEFAULT
• _REGISTRY_MACHINE_SAM
• _REGISTRY_MACHINE_SECURITY
• _REGISTRY_MACHINE_SOFTWARE
• _REGISTRY_MACHINE_SYSTEM
(THE QUESTION IS WHICH RPnnn to access)
sort the list by Date Modified until the newest one is on top.
Now then; how far back to you need to go? depends upon how much has changed
and how long did you suffer symptom. Choose a date far enough back to be
sure it's ok, but not so old that the programs you need were not installed
after that date.
the process is to COPY files to \windows\system32\config and
then RENAME them in place of the existing files (which you need to delete/rename first).
DEFAULT
SAM
SECURITY
SOFTWARE
SYSTEM
once they are rename, you can reboot
