My current OS installation is a Win 7 which has been updated to 8.0 then to 8.1 and now updated to 10. Time has come to make a clean Win 10 install.
I've just downloaded https://www.microsoft.com/en-us/software-download/windows10 and I'm stuck on the "Choose what to keep" screen.
It doesn't provide any information about what happens to my secondary harddrives that store all my data (the C:\ drive only contains the OS. I've moved user folders, apps and other stuff to other drives).
My gut feeling is that those drives will be left untouched by choosing "Nothing" but I would like to get some confirmation on that one before I continue.

1Windows installers have only ever modified the system drive. If you choose to keep nothing then any files on your system drive will be lost. You should be aware that Windows does not entirely support moving the folders you have moved, so your likely going to run into problems, if you choose to keep nothing. – Ramhound – 2015-10-06T13:30:51.140
1If you're worried, just disconnect any non-OS drives during the reinstall. And as always, before making any massive system changes, make a full backup. – Ƭᴇcʜιᴇ007 – 2015-10-06T13:35:17.267
If you keep nothing then you will have problems restoring your profile as it is now, because the new profile, will not be the same profile. This means you would have to take ownership of your current profile folder, and of course, duplicate your current settings again. You would be better off moving everything back to the system drive, doing the upgrade and keep everything, then moving stuff back where you want it. – Ramhound – 2015-10-06T14:16:40.893
