Hi,

Is dual booting with Windows 10 supported and if so, how to do it?

Thanks!

Hi. Welcome to GhostBSD. Dual boot is possible with GhostBSD. I've never tried it.
When you install GhostBSD, use the refind dual boot utility and everything should work. If you have problems ask here or on our telegram channel

I installed GhostBSD on a laptop with Windows 11 and refind dual boot utility. It works without problems. Just follow the installation instruction.
