Hello, My guess is that possibly-corrupted FAT filesystem. I assume that's your EFI filesystem, and it'll need to be correct in order to do most operations on it, and if it was unmounted uncleanly, that may cause the tools to fail.
Do you have other operating systems on this computer? do you have data on this computer that you care about? The possible ways this can go are complicated, it'd probably be best to look for help on irc (#ubuntu on irc.freenode.net) or something similarly responsive and experienced, to deal with your individual situation.
