reversing wallet to wallet transactions(both wallets mine) I sent BTC from my coinb.in wallet to an electrum wallet on a tails drive, but I didn't realize it was the tails iso disk, and while waiting for confirmations, I noticed id' used the tails iso disk after the transfer but before I could get confirms and send BTC back to the coinb.in wallet, Tails froze. 
So I had to reboot and that meant the tails iso disk went back to default, and the electrum wallet disappeared, so the BTC are stuck in blockchain because there weren't any confirms. 
There's got to be a way to reverse so the coins go back to my coinb.in wallet. Both wallets are mine, so, it would seem like the transfer could be returned/reversed as there's no merchant and its not a refund. Thanks
The "owner" of a wallet is defined by whomever controls the private keys in that wallet.  If you have lost control of a wallet (the one on the ISO disk), then you are not the owner of that wallet anymore.  Nobody is.

If the transaction to the new wallet has not yet been confirmed and put into a block, you might have the option of replacing that transaction with one that goes back to your coinb.in wallet.  That depends on two things:


The transaction you want to replace has opted-in to Replace-by-fee
Your original wallet (coinb.in) allows you to use Replace-by-fee to broadcast a new transaction, replacing the original one
