guideXOS

guideXOS is an operating-system exploring different runtimes, hardware targets, and CPU families For questions, updates, or collaboration: guide_X@live.com
Pick your path
guideXOS brings the desktop operating-system experience, while guideXOS Server pushes toward a multi-architecture systems platform for modern and revived hardware.
guideXOS
An operating system made entirely with C#
The original C#/AOT desktop operating-system project, with closely related Legacy BIOS and UEFI boot editions. Legacy BIOS is currently the more stable demo path, while UEFI remains an experimental bring-up target for debugging and future boot work.
guideXOS Server
An OS for a world beyond one CPU architecture
The independent native operating-system product line. v0.1.0 is now available as a bootable amd64 ISO with a graphical desktop, applications, file-management work, networking, and continued architecture development.
guideXOS Hypervisor
Experimental emulation and virtualization research
A future-facing research area for architecture emulation, VM tooling, debug workflows, and controlled virtualization capabilities across the guideXOS ecosystem.
Why guideXOS?
The original desktop branch still matters as a C#/AOT operating-system experiment with a visible UI and real apps.
Desktop OS Identity
guideXOS remains the original desktop operating-system branch under the umbrella, centered on a recognizable GUI experience rather than a kernel-only technology demo.
C#/AOT Experimentation
It continues the C#/AOT branch identity that made guideXOS distinctive, including Legacy BIOS and UEFI-related bring-up paths for low-level experimentation.
GUI, Apps, and Screenshots
Screenshots, desktop tools, and application work keep the project grounded in the user-facing side of OS design, not just boot code and subsystem internals.
Why guideXOS Server?
Built around portability, layered design, and evidence-driven systems engineering.
Strict Layered Architecture
guideXOS Server keeps the bootloader focused on loading the kernel, keeps the kernel boot-aware, and pushes desktop behavior into higher layers instead of taking shortcuts across subsystems.
Kernel Networking
The current kernel already includes Ethernet, ARP, IPv4, ICMP, UDP, TCP, DHCP, DNS, and a BSD-like socket layer for building real networking features.
Storage and Filesystems
guideXOS Server already brings up ATA, AHCI, NVMe, and USB storage along with FAT32, exFAT, ext2/4, and UFS support for practical boot and file access scenarios.
Universal Application Vision
The `.gxapp` container and its architecture-specific binary direction are active development work; broader universal application execution remains a roadmap goal rather than a v0.1.0 promise.
Real Hardware Paths
The project is tested through UEFI, BIOS, OpenSBI, serial consoles, framebuffer backends, and VM workflows so features can be validated beyond a hosted harness.
Architecture Portability
guideXOS Server is where the current multi-architecture platform work, UEFI/QEMU workflow, and portability roadmap are being pushed furthest today.
Try the released builds
Start with a public ISO; contributor build instructions remain in the Server wiki.
Download the guideXOS Server v0.1.0 amd64 ISO and try it first in a virtual machine or on spare, non-critical hardware. Preserve important data before bare-metal testing; hardware compatibility varies.

Open source and community driven
guideXOS Server is an active research project covering bootloaders, kernels, filesystems, networking, architecture ports, and future developer tooling. If you care about operating systems, low-level portability, or long-horizon application models, there is meaningful work to do.
