What do you get when you enter the command "dir flash:"?

It's either
1. the flash drive or the flash card is faulty;
2. someone inserted the wrong CF; or
3. someone deleted the CF
The quickest way is to eject the CF and insert it into a multi-card reader. If you have a windows client, format the CF using FAT16. Once format is complete copy the IOS from your client to the CF and re-insert the CF back to the router.
Otherwise, use this process:

1. Maximum size is 2Gb.
2. Not all brands/manufacturer supported. Try one and if it works, buy it.
3. If it works, format with FAT16 on a Windows client, drop the file into the CF and boot the CF.
