That's likely you forgot to adjust the path for initrd line in the
configuration file.
You need to change the path for every file referenced in the configuration
file.

For example, I have done that recently for Ubuntu 8.04
I move all files under ubuntu/x86/8.04/ inside tfpt root directory and add
/ubuntu/x86/8.04/ before every file names

This is the changed lines only

DISPLAY /ubuntu/x86/8.04/boot.txt

F1 /ubuntu/x86/8.04/f1.txt
F2 /ubuntu/x86/8.04/f2.txt
F3 /ubuntu/x86/8.04/f3.txt
F4 /ubuntu/x86/8.04/f4.txt
F5 /ubuntu/x86/8.04/f5.txt
F6 /ubuntu/x86/8.04/f6.txt
F7 /ubuntu/x86/8.04/f7.txt
F8 /ubuntu/x86/8.04/f8.txt
F9 /ubuntu/x86/8.04/f9.txt
F0 /ubuntu/x86/8.04/f10.txt

 kernel /ubuntu/x86/8.04/linux
 append vga=normal initrd=/ubuntu/x86/8.04/initrd.gz --
