Hi Eden,
The commands are different for different platforms. What kind of switch or router are you working on?
Here is a sample which I run for 4948E :
show bootvar ! to check what iOS is current loading
config t
no boot system bootflash:cat4500e-entservices- mz.150-2.SG8.bin
boot system bootflash:cat4500e-entservicesk9- mz.122-54.SG1.bin
exit
!
del bootflash:cat4500e-entservices- mz.150-2.SG8.bin
!
write mem
reload
I was removing cat4500e-entservices- mz.150-2.SG8.bin and loading cat4500e-entservices- mz.150-2.SG8.bin.
N.B.:- Make sure you backup your configuration before making any change.
