# NexBoot: diskless boot server for Windows and Linux
**Boot a whole internet cafe, LAN center or computer lab from one master image. PXE + iSCSI + ZFS in a single Go binary, with a web console and an optional HA cluster.**
**English** · 简体中文
## Why NexBoot
Keeping 50 or 500 PCs on the same Windows build is a chore. Every game patch, driver update or bad install means walking from seat to seat.
With NexBoot the PCs have no system disk of their own. They boot over the network, and each one gets its own writable copy of a master image. You update the image once. Every PC picks it up on the next reboot, and a reboot always brings a PC back to a clean state.
| Without NexBoot | With NexBoot |
|---|---|
| Patch every PC by hand | Patch one image, reboot the room |
| A broken PC needs a reinstall | A reboot restores it |
| Disks fail, PCs go down | No local system disk to fail |
| No easy way back after a bad update | Apply an earlier restore point in one click |
## Quick start
On an Ubuntu 22.04 / 24.04 server with a spare disk for the ZFS pool:
 [code] 
Then open `http:// :8080`, sign in as `admin` and follow the setup wizard:
1. Pick the network card that faces the clients.
2. Create a storage pool on the spare disk.
3. Import a Windows or Ubuntu image (`.vmdk`, `.vhdx`, `.qcow2`, `.raw` or an exported `.zfs` stream).
4. Create a group (IP range + image) and register the clients by MAC address.
5. Set the clients to boot from the network. Done.
No internet at the site? Use the offline bundle: `sudo ./install.sh` from `nexboot-offline-ubuntu24.04-amd64.tar.gz`. See Install for all options.
## How it works
 [code] 
- **Copy-on-write clones.** Each PC boots from a ZFS clone of a restore point. Clones cost almost no space and take a second to create.
- **Images, configs and restore points.** One image can have several configs (for example "esports" and "office"), and each config keeps its own history of restore points.
- **Super machine.** Boot one PC in edit mode, install your updates, shut it down and save the result as a new restore point.
- **Data plane stays local.** DHCP, `/boot` and iSCSI go to the node that hosts the PC. Nothing is proxied through a central controller.
