What I did instead of using the livecd,  for it would not let me switch 
to the root user, to authorizes  it, that from what I no it will not let 
you...

Anyway I then used Knoppix 5.1, everything worked fine, using grub, so 
when I at the grub prompt typed
grub> root (hd0,0)  It came up with this:
    Filesystem type is ext2fs, partition type 0x83
The I used this command:
grub> setup (hd0) it the said this:
Checking if "/boot/grub/stage1" exists...NO
Checking if "/grub/stage1" exists...NO

So it looks as though I have lost stage1 in the boot process...

Do you how I can fix that...???

Thanks Larry
