I realize that this will bring this post back from the dead, but I wanted to reply and let hemantsathe know that you are my hero!

I am the senior desktop support technician for a university and we image PCs using Symantec Ghost console. Occasionally we will have a machine randomly fail the setup process after imaging with this error and I always assumed that the machine needed to be completely reimaged to correct the issue. Reading your process made my day!

When windows displays fatal error message:

Shft + F10 = Command Prompt
cd c:\windows\system32\oobe\
msoobe.exe

Windows will then complete the installation (you'll be missing any custom accounts you setup in sysprep, etc but at least you'll be back to windows).
