Cisco ASA 5505: How to change the default OS

Hello,

I'm learning how to work on the Cisco ASA 5505. My machine has two OS images: the old 7. whatever image and a more recent 8.2 image. The 8.2 image is lower in the index on disk0 so whenever I reboot the machine, the start up points it towards the older image and I have to go into ROMMON to boot the newer OS. Could someone please guide me on how to change the position of the newer OS so that it's the default image? I'd like to do this without deleting the older image so that I can have a proof of concept.

Thank you!

Hi Colin,

You could use the 'boot system' global command to force the ASA to the pointed image file.

boot system flash:/image.bin
