Afaik, this exact issue is not answered here and I am too much of a noob to really follow this one: Installing elementary OS alongside Windows 10
So to my problem:
When it comes to choose the type of installation it says that I have installed Win 10 and how do I want to proceed.
But it DOES NOT give me the option to install it alongside Win 10.
The first option I have is to erase all and to install elementary.
Then I can enable the two tick boxes below (Encrypt and use LVM)
Then there comes the separation line and under that I can choose something different.
In all tutorial videos that i could find there is always a first option that says something like: " Install alongside existing OS".
I use an Acer TravelMate 5720 and Win 10 Pro 32 Bit. It´s fully registered.
Thank you all very much in advance for your ideas!
