Gleezor USB Installer Wizard

Build a single USB drive that contains the Gleezor OS installer and, optionally, a Windows VM template you supply. The Windows ISO you provide never leaves your computer.

Requirements

Windows 10 or later (Phase 1 host OS)
Administrator privileges (UAC prompt for USB partitioning)
16 GB USB minimum (32 GB recommended when bundling Windows)
Windows 11 ISO (optional) — downloaded directly from Microsoft

How it works

1
Download and run the wizard
Download the wizard from the download page and launch it. Accept the Administrator (UAC) prompt.
2
Choose a Gleezor version
The wizard fetches the official manifest and lists available Gleezor ISOs. Usually you pick "Latest stable".
3
Pick a Windows ISO (optional)
Select a Windows 11 ISO already on this computer. If you do not have one, download it from the official Microsoft links below.
4
Pick the USB target and start building
Only removable disks are listed. Acknowledge the warning, type ERASE, and start the build.
5
Install on the target server
Plug the USB into the target server and boot via UEFI. On first boot the Windows ISO is auto-imported as a VM template.

Windows® official downloads

Always obtain Windows installation media directly from Microsoft®. Gleezor does not host Windows files.

This wizard only copies a Windows ISO you obtained from an official Microsoft source onto your own USB media. Windows files are never transmitted to or stored on Gleezor servers.
