Cisco 3850 boot failure

[Raminkn20]

Hi, my 3850 is on install mode , i try to copy running config of other 3850 ( it’s on bundle mode) to my switch. After wr configs it doesn’t boot and try to find .bin file.

i can boot manually by “ boot flash:packages.conf” but after reliad i have same problem.

what can i do?

Because the boot variable string is still in Bundle Mode. 

Boot the packages.conf file again and change the boot variable string. 

conf t
 no boot system flash bootflash:filename.bin
 boot system flash bootflash:packages.conf
end
wr

Unfortunately after successful boot i tried to remove configs by “write erase” and installed other OS and reboot … now manual boot doesn't work too

What method was "installed other OS" conducted, Bundle Mode or Install Mode? 

I'm gonna suspect it is Bundle Mode.
