By windows authentication removed - do you mean that all windows accounts have been removed? (because AFAIK it's not possible to remove windows authentication entirely...)

Do you have the sa password?

If not - and you are an administrator on the server/machine try this:

Once you're connected to the instance with a sysadmin level account - you can add back windows accounts to your heart's content.

Yes but this did not work. get an error. See screen shot. And i also get another error say corrupt please reinstall inwhich I did reinstall. maybe should just remove the entire sql then reinstall. or do you think a system recovery would work?

I'm sorry - I can't really read that screenshot.

If you are able to reinstall SQL Server you can opt to add your current user account to the sysadmin role. (you can also create and remember the sa password)

How can I create a password when i cannot even connect?
Sa password not remembered.  Maybe uninstall the entire ms-sql then reinstall which will take forever.?

Well your options are, if you are an administrator on the local machine, you could follow the steps in the link above. I'm sorry but I couldn't read the screen grab you posted earlier - so if you have issues let me know...

Another option (which I've not personally tried) is:

A probably easier but more drastic solution is to uninstall and reinstall SQL Server. You'll be prompted for an sa password during the install.
