How do I install using premade partitions

I’m trying to set up a dual boot with clear Linux and windows, and according to the tutorial, I should make a 1gb efi partition. So I made partitions for swap, efi and Linux using gparted, but when I install clear Linux it deletes the partitions I made, and creates its own partitions automatically. How do I install onto my premade partitions?

Right now the installer detects unallocated space (not empty partition). Delete the empty partition on which you want to install the OS and then hit the refresh button. The installer should detect it.

But again the installer creates it’s own swap and esp partition.

I tried this way and I am unable to access my old Linux distribution. :frowning:
