The switch image seems to be corrupted.
try the following commands on the prompt
flash_init
load-helper
After this do a dir all and see whether u see any IOS file in the flash. If there is none proceed to X-modem image transfer

Hi!
I followed your instruction and got an error message as shown below:
The password-recovery mechanism is enabled.
The system has been interrupted prior to initializing the
flash filesystem. The following commands will initialize
the flash filesystem, and finish loading the operating
system software:
flash_init
boot
switch: flash_init
Initializing Flash...
flashfs[0]: unable to allocate available block.
...done Initializing Flash.
Boot Sector Filesystem (bs:) installed, fsid: 3
switch: load_helper
switch: boot
Loading ""...: permission denied
Error loading ""
Interrupt within 5 seconds to abort boot process.
Boot process failed...
switch:
What I'm going to do next? Did you notice the prompt after switch? It's colon instead of prompt.
Thank you for your reply.
Best regards

after flash_init and load_helper command can you try to do a Dir all and check whether you see any image file on the flash?
If not do xmodem and upload a new image and boot

Hello!
I followed instruction very carefully and got a message:

Thank you for your prompt reply.

Hi!
Thank you for your reply.
No problem, I can format the flash. But, since this my first time to format a flash, can you give me the safest procedure to do that first thing first? I don't like the problem to become worst or system unusable.
Once again thank you very much for your reply.
Best regards,

Hi!
It's currently copying ios after formatted the flash. I'll return to you when finished (shows 3.5 hours to finished) to give you the result.
Thank you for your reply.

Glad to know ur problem is solved.

if you have an IOS image on the switch try boot flash:(image name)at this switch prompt
Before giving you this switch prompt is it give you message that cannot load/find IOS something. you can paste that file name after flash: or u can see dir flash:to get the file name
If u dont have IOS or the current IOS on the switch is not working then u have to transfer through xmodem as mentioned in the other post
