Cisco 3850-12S software install question

lucas.shelton1

Just got a bunch of 3850's to replace our 3750's and I want to upgrade to the latest version of the OS.  Went online and downloaded 3.7.3E, installed it on USB then put it on the switch.

Once on the switch I did:

conf t

boot system switch all flash:cat3k_caa-universalk9.SPA.03.07.03.E.152-3.E3.bin

exit

write

reload

When it came back up I noticed the following message:

"The System is using a non-recommended Boot mode.
 Not all features may be available in this boot mode.
 Please check the product configuration guide."

Is there a better way to do this?

This may be a cleaner way  software install instead of IOS boot command

That fixed it with a couple tweaks.
