Windows 7: BSOD registry edit

hi guys,
a week ago i i got helped with a BSOD problem by changing some registry keys. I did it by puting the harddrive in another computer that was able to boot the harddrive. The problem i have now is that the hardrive wont boot on any other PC I put it in but i can access it if i boot from hirens. How can i change the regsitry keys in the drive by accessing its file system? please assist.

thanks so much guys in advance

I would recommend using the following steps to restore your registry:

• You will need a Windows 7 repair disc or you can use the Advanced Boot Options to get to the System Recovery Options.
  
  Then try the steps in Startup Repair Infinite Loop Recovery. Note the warning:

  The instructions presented withing this tutorial must be followed correctly, or you can damage your Windows 7 installation even further. This tutorial is designed to help recover from a bad registry that is causing the startup repair loop. You should note that there may still be some issues remaining that cannot be fixed by manually restoring the registry.

And please stop mucking around in the registry if you do not know what you are doing. As you've found out, it can have catastrophic consequences. If you are going to continue doing so, at least create a system restore point prior to making changes. Even better would be system imaging:

• Backup Complete Computer - Create an Image Backup
  
  
• Imaging with free Macrium
  
  
• Free Backup Software: Paragon Backup & Recovery Free Edition - Overview

If the registry restore steps I gave do not help, System Restore OPTION TWO may help.
