Bitcoin Core Reindexing

[Dubwise]

Hey everyone,
I'm new to bitcoin although I've been intending to start from some time now my wallet still has a year and 43 weeks of which given wifi speeds would take another two days of running;yesterday my laptop crashed leading to corruption of the blockchain hence I must reindex the BC- just in case this happens in the future I want to download Linux but any advice on how to reindex blockchains?.
Thanks

Please do not hijack threads and necro post. Make your own for your own issue. I have split this into its own topic

This should no longer happen with the latest version of Bitcoin Core. What version are you using?

hence I must reindex the BC- just in case this happens in the future I want to download Linux

Why? Linux won't help you here.

but any advice on how to reindex blockchains?.

Just click OK in the prompt that appears. If that does not appear, you probably don't need to reindex. When reindexing does happen, just let it run, there is nothing that you need to do.

Hi,
Sorry I will make such a thread now then; didn't intend to narco post.
I'm using 0.13.1v 32 bit.
Really no indexing required even if corrupted? I had no idea this was the case tried adding node but didn't fix,
Linux as saw a comment on this thread about that operating system dealing with crashes better by a forum user, was just in case my laptop crashes in the future as all.
My  wallet is currently saying no block chain available- it was working fine upon until the crash yesterday
I have 0 in 0 out also was 0 in 8 before
Thanks

How do you know that the blockchain is corrupted? The corrupted message normally comes with reindex prompt.

To reindex manually, start core with -reindex command. There's a tutorial on how to do it for in various OS here.
