Hi,
I really hope someone can help me with this.
I used to have a wallet with Multibit before they closed. They gave me a way to transfer my bitcoin to an Electrum wallet which I did.
Now I am trying to split my BTC from BCC, and by what I have read, I need my seed, which I cannot see in my wallet. The Seed option is greyed out.
Yes, you won't have a seed for any keys you imported from MultiBit Classic (not sure about HD). When you create any new wallets just using Electrum it will generate a seed for you, but if you import a private key, you just have the private key and nothing else. If you'd feel more comfortable using a seed, one option would be to generate a brand new wallet with Electrum, copy your seed down and store it securely, then send your funds from the wallet you imported from MultiBit to an address in your new wallet. You'd still have to follow all the steps to split your coins after doing this, though, so keep in mind that it's one more tx fee to pay if you decide to do that.
I'm not sure what you mean by "
my split". That 'Network' window shows where forks have taken place. There's nothing relating to you or your funds in there. Step 2.a is showing you which chain you're currently on and giving you the option to select a different chain, which is part of the procedure if you want to split your coins. It basically explains that if you put the block heights of each fork into a block explorer, you can tell which chain is which.
