Error: unknownfilesystem

When an error occurs during startup: unknownfilesystem -- general Linux technology-Linux technology and application information. For details, refer to the following section. Unable to enter the system when the system is started
Error: unknown filesystem
GRUB rescue>


Cause: install linux and XP on hard disks.

Today, I think the XP system has a problem with GHOST. I didn't expect to be able to enter the system.

The hard disk cannot be mounted to another host.
When the Windows XP system is mounted to another computer, the system cannot be mounted until the progress bar is reached.
The PE is still unable to enter the PE until the progress bar is reached.
The dostoolbox does not work either.

You cannot use a GHOST disk to enter pq ghost dos. You cannot even split the hard disk into four partitions with one click.

Now we have some tools on hand, a good computer, and an XP ghost system disk. There is nothing else. Find a solution.

It is best to save data !!! I have many things !!!
