Using The Bootldr Command - Cisco 7304 Quick Start Manual

The System Bootstrap message appears and the router loads an image from bootdisk. On the screen, you should see
something similar to the following:
System Bootstrap, Version 12.1(9) [biff-ws28 124], RELEASED SOFTWARE

Another option is to boot from an image copied from another router.

rommon 3 > boot disk0:c7300-js-mz (where disk0:is the flash disk with the image c7300-js-mz copied from
another Cisco 7304 router)
If you are still in ROMmon mode, that means your boot image is either missing or corrupted. If your router has no

valid image in disk0: or bootdisk:, and no other ROMmon upgrade procedure, the only way to recover is to use the
CompactFlash Disk on another 7304 router, download the image on that router, and then move the CompactFlash Disk
to the one with a corrupt or missing boot image.
If you do not have another Cisco 7304 router, call TAC to request a CompactFlash Disk with a valid boot image.

Using the bootldr Command

Use the bootldr command to specify an image to boot the system in the case of a system crash. You can use the bootldr command
in IOS or in ROMmon mode.
You can use the bootldr command in IOS:
Router> enable
Router#> config
Router(config)# boot bootldr bootdisk:c7300-boot-mz-my-image
Router# copy running-config startup-config
The show bootvar command can be used in ROMmon mode to verify that parameter settings are correct.
In cases where the system will not boot up, you can also use the bootldr command in ROMmon mode. First check to see if
bootldr is set correctly:
ROMMON> set
If bootldr is not set correctly, set it with the correct image:
ROMMON> BOOTLDR="bootdisk:c7300-boot-mz-my-image"
Be careful of typographical errors in ROMmon mode as there is no error checking.
Caution
You can use the ROMmon command sync to save the current parameters that remain after a power cycle to NVRAM.
Use the set command to check your configuration.
