user75884: I am trying to create altcoin(Abccoin) from bitcoin and change parameters in chainparams.cpp and also generated the genesis block hash and hashMerkleRoot but when I start the daemon with 
abccoind -daemon 
I get the error in debug.log :
ERROR: ReadBlockFromDisk: Errors in block header at CBlockDiskPos(nFile=0, nPos=8)

Using -reindex also doesn't solve the problem, then I got another error :
ERROR: AcceptBlock: high-hash, proof of work failed (code 16)

Does anybody know how to solve this problem?

user48884: The error means that your genesis block has an invalid Proof of Work.
