I posted this back in January:

  Is it a known issue that a 6509 (sup720-3bxl) with "too many" boot system
  statements in the config will confuse the boot loader, resulting in

  Autoboot: failed, BOOT string is empty
  Autoboot executing command: "boot "

  At this point, the unit boots whatever it can find in sup-bootflash.

It sounds like you've run into a similar issue.  I was running into this 
with around 5 or 6 boot statements.  I guess when upgrading, it's best to 
limit yourself to 2 boot statements (first choice and second choice).
