Greetings. Does anyone have an idea how one can edit and merge registry items into a registry file that is not currently installed? The non-working registry file (and Windows for that matter) is on a HDD and this HDD is now the secondary drive on some other computer just for the purposes of trying to repair the registry in question. Computer crashed after an over-zealous session using RegSeeker. (Yes - backups were made but they cannot be installed because this windows install has a corrupt C:\Windows\System32\Config\system registry file and cannot start. The computer cannot even get to the Command Prompt in Safe Mode or even in Safe Mode for that matter. There was no backup disk made and no Windows Disk. It is the Media Center Edition but they do have an XP Pro disk. The backup file from RegSeeker is in the .reg format. Thanks in advance.
