Error 13: Invalid or unsupported executable format
If I copy them to a bootable floppy then they will boot the OS just fine. But I cannot use Grub4dos to chain boot with them.
My solution was to use an ntldr from a Windows 2000 disk to chain boot Windows NT 3.51 with Grub4dos.
Is this older ntldr unsupported by Grub4dos?
