ISR 4331 does not boot to the image specified

[enewburn1]

New to IOS-XE but I have a ISR 4331 with two images on the flash. I've changed the configuration register to 0x2102 and I have the

boot system flash:isrxxx

in the startup config. The new image is listed before the old image in the config - but every time the router boots to the old image. Any thoughts?

Post the entire bootup process.

And then this.  The error message sounds like the IOS you wanted the appliance to boot is either corrupt or not available. 

Can you please compare the MD5 hash value of the file you've downloaded against the MD5 hash value found in the Cisco website?  Make sure they match.  

Run the command

verify /md5 bootflash:filename.bin

to determine the MD5 hash value is.  Alternatively, if go to the Cisco website and copy the MD5 hash value, go to the router and run use the command

verify /md5 bootflash:filename.bin

<MD5 hash value from the Cisco website>

.  If the MD5 hash value matches, you should see "Verified!" at the end.

Hey Leo,

I ran the md5 Verification and it did match what is on Cisco's website. (bafa359295bf28329dbc57bb0ae92c9f) Just to be thorough I also put on a much older image and told the boot system to go with that one. It too, failed

[Leo Laohoo]

Hmmmm ... May I ask if you can provide the complete output to the following commands: 

1. sh version; 

2. dir; and

3.  sh run b | i boot

[enewburn1]

Yes Sir

boot system flash:isr4300-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin

I think this syntax is incorrect.  

Can you try the following: 

config t
no boot system flash:isr4300-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin
boot system flash bootflash:isr4300-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin
end

Thank you Leo! You were right - IOS XE wants

bootflash not just flash.

Everything works fabulous now. 

[Leo Laohoo]

Thank you very much for providing the feedback and ratings.  :)

[Leo Laohoo]

Oh, I forgot to ask:  If you've upgraded the IOS, did you also upgrade the bootstrap?

[psnyder1985]

I had the same problem and was simply missing bootflash. Thanks!

Providing bootflash: in the filename fixed this issue.  This just seems like an extra step for no reason to me, very...ridiculous to say the least.

Cisco appliances, particularly routers and supervisor line cards, have their CF partitioned in different ways.  Some use bootflash:, some use flash:.  At the end of the day, without the "bootflash:" (and just using "flash:") instructs the system to look into a partition called "flash" and boot the file there.  Since there is no partition called "flash", then the appliance goes into ROMmon.
