Is there anything I need to do?
It depends what your plan is.
Do you want to keep Vista and dual boot Mint?
Do you want to install Mint and remove Vista?
Do you want to install Mint inside Vista?
If you want to keep Vista and dual boot Mint, there are
some very specific steps to follow, otherwise you'll
end up with an un-bootable Vista system.
The other 2 options are more straight forward.
Let me know if you need more assistance.
Things are more like they are now than they ever were before.
