cisco cat 4507R with sup iv IOS upgrade problem

hi all,

I have cisco catalyst WS-C4507R with suoervisor (WS-X4515) with IOS (cat4000-I9K91S-M) I need to upgrade it to the latest IOS (150)

when I download the IOS from cisco site and copied it on the bootflash: and force it to boot from this image (this displayed in the output of show bootvar)

I reboot the box then when started up I found that it not booted from the required IOS and boot from the old IOS.

any help please

Hi,

First check with "sh boot"  command, most likely the old version is still in the boot variable.

Than deleted the old boot variable command and than add the new one, save and reboot.

no system bootflash

system bootflash
