The bootvariable is set incorrectly. Remove the existing one and add the following statement.

conf t

boot system flash bootflash:cat4000-is-mz.121-13.EW.bin

[MJonkers]

how do I remove it?

[Prashanth Krishnappa]

do a sh run. Your incorrect bootvariable should be something like "boot system flash:xxxxx"

Issue a "no boot system flash:xxxxx" from config mode
