I’m trying to replace my Manjaro install with EOS, but Windows 10 (for dual boot) isn’t detected during installation. There are two SSDs, one with Windows and one with Linux.
The EFI partition is on the Windows disk. If I select “Replace a partition” during setup, the EFI partition is detected. It shows up in the drop down menu on the bottom of the installer window. However there is no indication Windows is detected to enable dual boot.
From fdisk:

I found this thread, and I could probably do that to make it work after the installation if there are no other options.
Any help is appreciated.
Edit: Or isn’t there any confirmation in the installer that Windows (or other types of OS) is detected for dual boot?
