Boot Problem after Copying new flash and changing boot system

Im currently upgrading the routers IOS because of the recent discovery of the Cisco IOS IP Version 4 flaw. I download the recommended flash image of all the routers I got and have started upgrading some of my routers. Today I got a problem with one of the 1700 I did upgrade. The old image on the router is c1700-y-mz.122-8.T5.bin and the one I downloaded and copied(using TFTP) to the router is 1700-y-mz.122-8.T10.bin. Since I have enough flash memory I didnt delete the old flash image for safety. And this is what I did. I copy the new image and I change the boot system of the router so that It boot from the new one first and if it doesnt work then boot from the old image.

This is the command I use:

(config)#boot system flash c1700-y-mz.122-8.T10.bin

(config)#boot system flash c1700-y-mz.122-8.T5.bin

However when I reload the router it comes up with the following:

Re: Boot Problem after Copying new flash and changing boot syste

it looks like it is loading the new image and it is either a corupted image or you are hitting a bug.

to load the old image connect to the console while it is booting up break in to the box with a break sequence , then the box should go to rommon>

at the rommon> prompt change the config register to 0x2142, the reset it should load the first image in flash, from your boot statements it does not look like the flash is partitioned so it should load the first image.

If that fails from the rommon prompt do a

rommon>boot flash:c1700-y-mz.122-8.T5.bin

Thanks. Is it possible if you could list the step by step. That will really make it easier for me.

Re: Boot Problem after Copying new flash and changing boot syste

That really solve my problem. On romon 3 >I boot from the old image and remove the boot system command. Then I erase flash and then copy the new one.The new image is not corrupt. It works fine now.

I think its the boot system itself was the problem.

One question.Do we need to add this command "boot system" and then add the commands "boot system flash:flash image name" when we have two flash image and want to prioratize the boot system ?

for e.g

(config)#boot system

(config)#boot system flash c1700-y-mz.122-8.T10.bin

(config)#boot system flash c1700-y-mz.122-8.T5.bin

with the first one as my prefered image

Re: Boot Problem after Copying new flash and changing boot syste

you do not need the

(config)#boot system

it is most likely what hosed you up .

you need to have boot statements if you have more than 1 image in flash and it is not partitioned .

without boot statements the box will load the first image it sees in flash .
