cannot get into windows

[rojola]

I recently compressed some files in Norton to make some room. When I rebooted, I could not get into windows. I can go to a C prompt but trying to get into windows doesn't work. When I reboot in safe mode , I get the message: While initializing device VFBACKUP:VFBACKUP could not load VFD.VXD. Please run setup again.
I downloaded vfd.vxd but have no idea where to put it.
When I reboot in normal mode I get the blue screen with: Invalid VXD dynamic link call from VDHCP(03) + 000022FE to device "0489", service 7.
Your windows configuration is invalid. Run windows setup program again to correct this problem.
Unfortunately the problem is never solved. Is there anybody out there who can tell me what to do? I'm hoping I can get into Windows and access Norton to fix the problem.
