is there any step by step guide/commands/video to start the bitcoin fork. The fork should be same as bitcoin with just the change in name, logos and nodes.
You mean something like this
https://forkgen.tech/If you want to do it yourself, you'll need to do something like this,
You need a new genesis block.
You need a different address byte (e.g. bitcoin uses 0).
You need to change the default port and rpc port.
You need a way for clients to find one another. You can run a DNS seed.
You need to change the "backup client list" which is a bunch of 32 bit integers which represent IP addresses.
You need somebody to mine initially, because otherwise transactions won't confirm.
You need to alter the default datadir directory.
You need to change the magic number in the protocol header, otherwise your client might connect to the Litecoin network by accident, wasting bandwidth.
You need to change the alert keys, otherwise the Litecoin devs can send alerts onto your network.
Add a transaction to the UTXDB which is your premine transaction
