I'm getting the following message: device does not contain a valid magic number boot: cannot open "bootflash:" an alternate boot helper program is not specified (monitor variable "BOOTLDR" is not set) and unable to determine first file in bootflash loadprog: error - on file open boot: cannot load "cisco2-C4500" I combed the CCO, no luck.
