I have a bootflash in 4507R with the size of 60MB. I upgraded the ios from cat4500-ipbasek9-mz.122-37.SG1.bin (12.8MB Size) to cat4500-entservices-mz.122-37.SG1.bin (13.8 MB SIZE) and deleted the previous IOS.
But previous IOS is still getting shown in sh bootflash: command. Furthermore, dir bootflash: commands shows there is only one IOS , which is running. Please Help, how I can free the space from bootflash , as I again have to upgrade the another new IOS ( of 16MB), which I tried through solarwinds tftp and couldn't upload successfully because of its limitation. Now, If I try to upload the new IOS through FTP, it gives me memory space error. Please help, how I can free the space captured by old IOS and also how I can delete the 3rd unknown entry of IOS (shown below output of commands)?
