If this error occurs, temporarily disable the 386MAX commands from the startup files, and then run Setup again. When running Windows 95 Setup from MS-DOS you might receive this error, indicating there might be a conflict in the upper memory region. Or run Setup from Windows 3.x. Setup requests a new source path. If that doesn't work, shut down and restart the computer.
Setup is unable to find a valid boot partition.
A valid MS-DOS partition must exist in order for Setup to install Windows 95. If Windows 95 Setup is unable to find a valid boot partition during installation, it displays an error message. If you receive an error message, there might be an actual partition error, but it is more likely that disk compression software or network components are mapping over the boot drive. This might occur if you are mapping a network drive to E, but E is the hidden host drive for your disk compression software, or you are using a LANtastic network and drive C is being mapped or shared. If no valid partition exists, take appropriate drive or data recovery efforts.
