Dual Boot EASY Guide

[pelephant2]

This is a public service announcement. As of Omarchy v3.2.3 dual booting with Windows (assuming you have two drives) is getting easy. Here's all you need to do:

1. Prepare your PC by disabling Secure Boot and TPM in the BIOS and installing Windows on one of the drives, then disable Windows fast startup
2. Download the Omarchy ISO, put it on a USB stick (use balenaEtcher on Mac/Windows or caligula on Linux), and boot off the stick. Install to your second hard drive.
3. Boot into Omarchy, open a terminal and issue the command sudo limine-scan
4. Select Windows to add it as a Limine entry in the boot loader
5. Reboot. See bootloader entries for Linux, Windows, etc. Done

Previous guides I've read are a lot more involved but this is all I had to do to get things working.

@pelephant2, I followed this guide, but now when I try to boot Windows via the Omarchy bootloader it goes to a Bitlocker recovery screen. If I boot to Windows from the bios it works fine.

If it's asking for the recovery key, it most likely was not disabled on the drive/partition. I ran into the same issue and removed bitlocker on the Windows partition. If you have your recovery key, just type it and once you're on Windows, disable botlocker

I followed these steps, working for me with no apparent issues.
