how about step by step confirmation and let us know? probably barfs when the symantec stuff loads??
if step by step won't help you boot, you will next need a boot floppy, either a winme startup disk or win98 startup disk preferred...
then you can boot from floppy and navigate to c:\windows and try a scanreg /restore (from a command prompt in the windows folder).
second, here is overview of working with registry file backup copies.
from TechTV website:
Every time your computer boots up successfully, Windows 95 creates backup copies of its Registry files. These backup files, System.da0 and User.da0 (zero, not the letter O) are hidden files in the Windows folder.
If you don't have system.da0, check to see if you have another backup of the registry file. To do this, type dir system.*/s at the C: prompt. Note that a registry backup should be at least 1MB in size, usually 2MB.
If there is one, copy it to c:Windowssystem.da0.
To restore your Registry from Windows 95's backup files, start by choosing Shut Down... from the Start menu. When the Shut Down Windows prompt appears, choose Restart the Computer in MS-DOS Mode and click OK. Your computer will reboot to the DOS C: prompt.
Next, switch to the Windows directory by typing cd windows and pressing [Enter]. The DOS prompt should now look like C:WINDOWS. At this point, issue the following commands, pressing [Enter] after each:
attrib -h -r -s system.dat
attrib -h -r -s system.da0
copy system.da0 system.dat
attrib -h -r -s user.dat
attrib -h -r -s user.da0
copy user.da0 user.dat
Finally, reboot your computer a second time.
