Original report
What's wrong
Dual-boot install. Before running the Omarchy installer, I manually partitioned the target disk with fdisk/cfdisk, creating a dedicated partition and setting its type to EFI System Partition, then wrote the table and exited.
When I ran the installer's "quick installation" flow, it did not recognize or offer that pre-created EFI partition at all — it behaved as if it expected a complete/whole disk to work with, rather than detecting and letting me select the existing ESP I'd already carved out.
Expected
"Quick installation" should detect pre-existing partitions (especially one already flagged as an EFI System Partition) and either reuse it automatically or offer it as a selectable option, instead of only supporting a full-disk layout.

This looks like it's in the same neighborhood as a few other partition-handling reports:
- #7515 — free-space/alongside-existing-data install failing with non-OS partitions present
- #7867 — dual-boot install creates a redundant ESP instead of reusing the existing one
- #4579 — after install, only "EFI fallback" shows in the boot menu, other OS entry missing
I don't have the installer's source on hand to point at the exact detection logic (it runs from the live ISO, not shipped in the installed /usr/share/omarchy tree), so this is filed as a user report rather than a traced root cause — but the pattern across these issues suggests the "quick install" partitioning step generally doesn't account for partitions a user has already prepared ahead of time.
System details
Dual-boot install, disk pre-partitioned with fdisk/cfdisk (EFI System Partition type set manually) before running the Omarchy installer.
