Confirm the hard disk has sufficient free space.
The hard disk in your computer is formatted with FAT32. You cannot read or
write data formatted in other operating systems, which are not FAT 32
compatible. Applications that are not compliant with FAT32 may not work
properly.
If you cannot re-install Windows 98 correctly, check whether the item Fixed disk
