I did a "df" and it returned info showing : /dev/hda1 was mounted on "/boot". May be irrelevant.
going back to the suggestion that started this: using dd to write 510 bytes to hda1 won't wipe out the mbr. It has to be hda
I can't imaging dd refusing to write to the raw device--were you running as root
If /dev/hda exists, then dd if=<something> of=/dev/hda WILL work!!
But, you again describe the issue the you cannot boot from the Windows CD. wiping the mbr won't help with that....
