Ok @hamza-ali 

You perform a 'wr' before reload ? sorry for that question...

[M02@rt37]

Try also to add this command and test reload after modify also the config-regsiter value:

no system ignore startupconfig switch all

If the switch is in ROMMON, please post the complete output to the command "set".

Thanks Team,
Issue got resolved to run this command in global configuration mode:

config terminal:
no system ignore startup config switch all
then,
Privileged mode:
copy startup config.

reload
