Install on a partition.

I want to dual-boot Windows and Omarchy, but I only have a single drive. How can I install Omarchy onto a specific partition instead of having the installer format the entire disk?

You should watch no signal youtube channel, he has maked an omarchy iso from it you can dual boot windows and omarchy I am also using it right now and it is working without any issues. He has a website also no-signal.uk .

The installer supports this now: shrink the Windows partition first (Disk Management → Shrink Volume), then in the installer, after picking the disk, choose Free space install so it doesn't wipe the drive. Afterwards run limine-scan to add Windows to the Limine menu. BitLocker has to be turned off first, since it encrypts the whole drive.
