It seems your configuration file contains a reference to a boot image that no longer exist.
I recommend trying the following:
#rename flash:config.text flash:config.old
#boot
>enable
#rename flash:config.old flash:config.text
#copy flash:config.text system:running-config
#dir flash:
Write down the IOS image
#show run
replace the boot system variable to match the IOS image listed in the flash folder.

Hi,
The switch is not having any IOS image files in the flash! [flashfs[0]: 0 files, 1 directories ] Or maybe you have one in the directory that you have there.
You need to copy an IOS image into the flash, so that you switch can boot with it! Copy a file into the flash and boot with it.
Have a look at the following link:
Hope this helps!

SKRAO,
See the reason for the error below. Appears, you mayn't have a valid IOS and you can copy a valid image using xmodem function.
Getting "Error Loading Flash" error messages.
The error loading Flash message means that there is a problem loading the current image in Flash memory. The image could be corrupt or incorrect, or the image in Flash memory could be missing. If the system is unable to load a software image in Flash memory, the system will load the boot helper and bring up a switch prompt.
1. Enter the dir flash: command to verify if there is any bootable image on the Flash memory. The file with the .bin extension is the bootable image on the Flash memory.
If you see a bootable image on the Flash memory, continue to Step 2. If you do not see any bootable image in the Flash memory, download the IOS Image File by using X-Modem.
2. Enter the set BOOT flash: name of IOS file command to set the boot variable to the filename displayed in Step 1.
Note BOOT must be capitalized and make sure to include flash: before the filename.
3. Enter the boot command.
Note If the switch boots properly, enter the setting boot parameters global configuration command to verify and set the BOOT parameters (if needed), and proceed to Step 4. If the switch fails to boot properly, download the IOS Image File by using X-Modem.
4. After setting the BOOT parameters, reload the switch by entering the reload privileged EXEC command.
The switch boots up automatically with the correct image.
HTH,
Sundar
