Registry dies...

I have somehow stuffed up my registry, and have no backup. My system now boots partially, displays the Win95 splash screen, then just hangs, mouse frozen in the centre of the screen, on black background.

Next time I boot, I get the screen with the options to run in safe mode, etc. None work. I can boot to the command line OK, but what does that get me? I don't have a working registry to import, so Regedit can't help me. Running in step-by-step confirmation doesn't help - all my commands run fine until i get to the WIN command, at which stage it just hangs, same as if i booted normally.

I REALLY don't want to reinstall - i would lose so much stuff. Is there any hope?

Boot your computer with a disk (if you have FAT32, you must take a Win95 bootdisk).  You can find under the windows-folder the files system.da0 and system.dat (hidden!!, with attrib you can unhide it).  Move the system.dat to somewhere else.  Rename te system.da0 to system.dat.  Try to reboot.
If this won't work, try the same with the user.da0 and user.dat files.  And if this doesn't work any more...
Their is also a little hope...    Under the root their is a file named system.1st.  (it's hidden, with attrib you can unhide it).
Rename this file to system.dat and copy it to c:\windows.
Now use have your systemconfiguration like it was just after the installation of windows.  (i think you need to reinstall the moust of your app's).
If this won't work anymore... i think their is no real hope anymore...
Note:  before you wanna work with the registry, copy user.dat and system.dat on a safe place!

Almost perfect - only problem was resetting the attributes of the system files - ATTRIB wouldn't do it. I had to boot my NT partition and set them there. Other than that, worked fine. Thanks, MSOLS

Under the windows\command directory was a ATTRIB available... But the main case is that your problem is solved :)

yes, ATTRIB was there, it just didn't work. But as you say, my problem is solved - I only mentioned the ATTRIB thing for your interest. Thanks a lot!
