Every release is published on GitHub. Downloads are plain files — no installer, no sign-in, no tracking.

Build it yourself
This is the recommended route while the project is young, and it always gives you the current state of the tree.
git clone https://github.com/Enclica-Forest/Forest.git
cd Forest
export FOREST="$(git rev-parse --show-toplevel)"
Then let the build tool do the rest — it installs missing host packages, builds the cross-toolchain, compiles userspace, assembles the initrd and produces bootable images:
./createos.sh # menu-driven
./createos.sh --quick # 32-bit BIOS, defaults, no questions
Building the toolchain is the slow part, and it only happens once.
If you'd rather drive the build yourself, the Docs page has the step-by-step sequence, and MAKE_AN_OS.md covers every option.
What a build produces
| File | What it's for |
|---|---|
forestos-bios-32bit.img | Raw BIOS disk image — write to a USB stick or boot in QEMU. |
forestos-uefi-64bit.img | Raw UEFI disk image. |
forestos-bios-32bit.iso | Hybrid BIOS + UEFI ISO. |
esp.img | EFI System Partition, for UEFI boot. |
Running it
Easiest route, from the fern directory:
make run
Or drive QEMU yourself. The BIOS build is a raw disk image, so it goes in as a drive rather than a CD:
qemu-system-i386 -drive format=raw,file=$FOREST/foreboots/build/forebo.img \
-serial stdio -vga std
Writing it to real hardware
Write the whole image — it already carries the bootloader stages and the kernel:
sudo dd if=$FOREST/foreboots/build/forebo.img of=/dev/sdX bs=1M conv=fsync
sync
Check the device node twice. dd to the wrong one
destroys whatever is on it, with no confirmation and no undo.
Please don't install this on a machine you need. Forest OS is a work in progress. It comes with no warranty of any kind — see sections 15 and 16 of the GPL v3.
