why can't boot

I have made a boot image boot.ifs ,it can boot from floppy .but i copy it to
the harddisk like this: cp boot.ifs /hdc/.boot(/hdc is the bootable partition of harddisk ),during booting after some …,it displays ‘S’,what’s wrong ?
the floppy bootable image can’t be used to harddisk? Should the partition be type 79 (not the type 77)?I use VMWARE to run above

anyboady can help me?

perhaps this article can help you:

at least it explains that
If S appears at the end of the dotted line, no OS signature is found.

How should I do?I have a floppy bootable image
