Changing the boot preference on a Cisco 1921 Router

[hclaster1]

I have a Cisco 1921 router that I am trying to program, but it is booting to USBFLASH0: and not FLASH0:

How can I change the boot option so that it boots to where I want it to

Try;

boot system flash <the name of the ios>

verify with show boot

I have tried that, did a reload and then a show run | include boot and it is showing the correct boot. 

But when I do a Show version the results show boot system usbflash0: filename

ok, than first do the no command for the USB

no boot system usbflash0: filename

than add 

boot system flash filename

BTW, for it to take effect, you have to reboot the router.
