wrong installation (Kali linux on windows 10)

Hello, following the advice of a colleague I tried to install kali linux. I did no matter what. Basically, I wanted to install kali linux on a virtual machine and in the end I launched an installation directly on windows. I now have a linux installation residue on my pc when I restart it I am offered to start windows (10) or to "continue installing kali linux. Now, if possible, I would like to" uninstall " linux, which is not to install 100% and then install it on a virtual machine, as I should have done from the start to get my hands on it. Thanks in advance! Anthony
