Fyde os 18.1 3rd gen 7rd gen media installation problem

I installed fydee os. But I can’t install it on the hard disk. The screen where I will select the hard disk did not appear in the installation. I am currently using fyde os. Where does this operating system work from? I want to delete windows and continue with fyde os, but I can’t select the disk. How can I do it?

UEFI in BIOS and GPT partition

I tried creating media with rufus and it worked. Ventoy can sometimes cause problems, you can close this topic.
