My wallet runs fine on windows 10 - with one exception: on every boot it says: blockchain cannot be loaded and I have to sync it every time...
Have to admit: Wallet and data directories are on another harddrive and direcotry (intern), so no "%appdata%"
Can I do something so I don't need to sync the wallet on every reboot?
Currently we have a very large amount of wallets running all around the world and nobody has ever reported this issue.
My best suggestion for you is to submit this issue with as many details and documentation as possible here:
