If the flash has been deleted / formated and there is no IOS on the switch or router, you have to copy the new IOS via the console port. this article explains the procedure using teraterm

rommon 1 > xmodem -c filename.bin
Do not start the sending program yet...
File size Checksum File name
18699016 bytes (0x11d5308) 0x7234 c2600-is-mz.122-15.ZJ2.bin (bad checksum: 0x6683)

WARNING: All existing data in bootflash will be lost! Invoke this application only for disaster recovery. Do you wish to continue? y/n [n]: y
Ready to receive file filename.bin ...

now send file by clicking on the top menu: file-> transfer-> send-> xmodem - and chose the file from your local directory
the transfer should start now.
