have you set the new boot variable to boot with new image

post  the out put :

show boot

dir bootflash:

or 

you can follow this guide.

Make sure you do all the task of upgrading the OS in change window always preferable.

So the old IOS file is still in the flash?
Have you tried deleting this? Maybe the "squeeze" command is needed?
Post the complete output to the command "dir bootflash:".
