I'm Being Unable to Upgrade New IOS in Catalyst 4948E-F Switch

I have Catalyst 4948E-F Switch. It is booting in ROMMON mode. I tried to upgrade with new IOS. It Shows a message that "File Loaded Successfully" but not showing in BootFlash Directory. I would be very grateful if anyone will solve this headache. 

 

Here is BootFlash Directory:

 

rommon 2 >dir bootflash:

Post the entire boot-up process so we can see what is going on.

Read back invalid SEEPROM-1 data : is the SEEPROM programmed?

For help on choosing a boot method, type 'confreg' command.
rommon 1 >

Try this: 

confreg 0x2101

And then reboot the switch.

rommon 1 >confreg 0x2101
usage: confreg

I have tried this command and reboot the switch but didn't work.

Try this: 

boot bootflash:cat4500e-ipbasek9-mz.151-2.SG.bin

rommon 1 >boot bootflash:cat4500e-ipbasek9-mz.151-2.SG.bin
boot: can not load "bootflash:cat4500e-ipbasek9-mz.151-2.SG.bin"

This Command Is Also Not Working !!!

boot flash:cat4500e-ipbasek9-mz.151-2.SG.bin

This is also not working. Is there any way to delete old IOS from switch? in ROMMON mode I cannot use "erase" , "delete" , "format" command.

When you were typing the commands, did you use the "backspace" or the arrow key(s)?
